Abstract:

Friedel–Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.

Abstract:

A convenient synthesis of the central core of helioporins, seco-pseudopterosins and pseudopterosins in racemic form is reported, using a Suzuki coupling (A-ring formation)-Friedel-Crafts acylation sequence, followed by synthetic elaboration of the resulting tetralone derivative. Key steps of the method are a totally diastereoselective cuprate conjugate addition and a final, spontaneous Friedel-Crafts acylation.

Abstract:

The work contained in this thesis covers the sulfonylation reaction between toluene and one of methanesulfonic anhydride and methanesulfonyl chloride. The desired products of these reactions are the three isomers (onho. meta and para) of methyl tolyl sulfone and the by-products are methanesulfonic acid, when methanesulfonic anhydride was used as the sulfonylating agent, and hydrogen chloride when methanesulfonyI chloride was the sulfonylating agent. When this reaction was carried out using the traditional Friedel-Crafts catalyst, AlCl) the thermodynamic isomer ratio of 60 % ortlw, 30 % para and 10 % meta was obtained. The aim of this work was to increase the selectivity of the sulfonylation reactions to the para isomer as this was required by the industrial partner (Zeneca) for use in further reactions. The two sulfonylation reactions were carried out over a range of catalysts including Alell , a silica-alumina, a montmorillonite clay and several zeolite catalysts. The main catalyst studied was zeolite Beta as in an empirical test of a range of catalsyts it had given the greatest percentage of para isomer, with a selectivity of 60 per cent obtained under certain conditions. Reaction times, temperatures and stoichiometry were amongst the variables investigated for their role in the reaction. It was found that the reaction had an initial induction period whichever solid-acid catalyst was used, and also that the reaction stopped by twenty four hours, presumably due to catalyst coking. Yields of methyl tolyl sulfone of up to fifty per cent with a selectivity of sixty per cent for the para isomer were obtained using zeolite Beta with some catalysts giving higher yields but correspondingly lower para selectivities. The catalysts were studied using a variety of analytical techniques. The analysis of the catalysts, particularly for a series of well-characterised zeolite Y’s, was compared to the catalysis results and several interesting trends were observed. The Sil Al ratio of catalysts did not have a consistent effect on the yield or selectivity, however the amount of extra› framework aluminium was shown to have a near-linear relationship to the yield. The disproportionate yield in the sulfonylation reaction for zeolite Beta was linked to the ability of zeolite Beta, much investigated recently, to have very mobile aluminiums either in the framework or dislodging from the framework. These act as Lewis acid sites.

Abstract:

The various inorganic solids that may be employed as heterogeneous catalysts in organic reactions are discussed in Chapter 1. In the present climate, heterogeneous catalysts are seen as more environmentally acceptable alternatives to homogeneous Lewis acid type catalysts. Chapter 2 describes the Friedel-Crafts acylation of aromatics. Discussion focuses on both the classical and solid catalysed reactions. The study of a pharmaceutical intermediate is described in Chapter 3. The aims of the work described were to develop an efficient and commercially viable process for the production of 1-(4-methoxyphenyl)-2-phenyl-1-butanone by the acylation of anisole over a suitable heterogeneous catalyst. In Part A of Chapter 4, the acetylation of a range of 1,2-disubstituted aromatics over solids is discussed. Part B describes the use of different anhydrides in the acylation of 2,3-dihydrobenzofuran over a number of solids to elucidate the generality of the reaction. Investigations show the influence of the solid catalyst and the effective recovery and regeneration of a zeolite catalyst. Finally, the acylation of 2,3-dihydrobenzofuran with ethyl oxalyl chloride over heterogeneous catalysts is described in Chapter 5. The reaction proved difficult with close consideration given to the reasoning behind the poor performance of the reaction; a good case in point being the amount of material unaccounted for in certain experiments. Investigations led to the isolation and characterisation of what were considered to be likely by-products of the reaction. Efforts were made to reduce the likelihood of such by-products being formed and with further attention, a yield of 73% of the corresponding para acylated product was formed in the presence of zeolite Hβ after 7 days. Having speculated that the difficulties encountered during the study of this reaction may lie with the nature of the acylating agent, the use of mixed anhydrides based on ethyl oxalyl chloride as potential acylating agents was investigated.

Abstract:

A study has been undertaken to establish whether it is possible to introduce unsaturation into Friedel - Crafts ( F/C) polymers, so that they can be cured free - radically via the unsaturation. It was hoped that the hydrocarbon - only nature of the polymer backbone, and the absence of hydrophilic cure catalysts would produce a material of low water absorption. The introduction of unsaturation has been approached in two ways. The first was to synthesize Friedel - Crafts prepolymers with ethyl side - chains. The side - chains were then tb be chlorinated, and then dehydrochlorinated to produce vinyl unsaturation. The introduction of vinyl unsaturation by this method was concluded to be unsatisfactory, due to the ease of premature crosslinking of the vinyl polymer during dehydrochlorination. The second method of introducing unsaturation was to include an allyl aromatic monomer in a F/C polymerisation. Such allyl F/C prepolymers were successfully prepared, characterised, and crosslinked. The need for a high cure temperature, and the consequent ease of oxidation make the radical cure of the allyl polymers inconvenient. They may be cured at lower temperatures, without oxidation, by cross linking them via a cationic mechanism. A study of the 13 C NMR spectrum of an F/C polymer has yielded new information on the branched structure and on the routes by which the polymer is built from monomer units.

Full text

Abstract:

Alginates are polysaccharides derived from brown algae, available in nearly unlimited amounts at very low prices. In the presence of some divalent metals, these renewable biopolymers can readily form hydrogels, solvogels and aerogels, characterized by high surface areas, good mechanical properties, tolerance to different media, and easy manageability. For these reasons, alginates are nowadays being thoroughly studied in heterogeneous catalysis; several applications in supported metal catalysis and as heterogeneous Brønsted acids have emerged. However, none of these studies has given an answer to the following intriguing question: can we use the intrinsic chirality of alginates to induce enantioselectivity in a chemical reaction? In order to answer this question a representative reaction, the Friedel-Crafts alkylation of nitroalkenes with indoles, was tested in this master thesis. This study, which involved a large screening of a variety of alginate gels under different reaction conditions, showed that Cu2+ and Ba2+ are the best cross-linking metals to promote the Friedel-Crafts reaction. Indeed, good activity with moderate enantiomeric excesses were obtained under the optimized reaction conditions. Furthermore, these two metals allowed the access to both enantiomers of the products, an important aspect given that only one enantiomeric form of alginates is available. Finally, the heterogeneous nature of the catalysis by one of the two gels was proved, and a good recyclability was demonstrated, by showing that the same catalyst can be used at least five times with similar results.
