Abstract:

A study of (E)-2,3-dimethyl-2,4-hexadiene (E-3) and (Z)-2,3-dimethyl-2,4-hexadiene (Z-3) by the semiempirical computational method AM1 and He(I) ultraviolet photoelectron spectroscopy (UPS) has established that this combination of AM1/UPS will be generally useful for detailing conformational and electronic properties of alkyl-substituted 1,3-dienes. This method was used to elucidate the structures of the stereoisomeric 2,4-dimefhyl-2,4-hexadienes obtained from the photolysis of 1,3,3,4-tetramethylcyclobutene (2). Keywords: 2,3- and 2,4-dimethyl-2,4-hexadienes, conformational analysis, AM1, He(

Abstract:

3-(Diethylphosphono) substituted 1,5-hexadienes are prepared by the α-regioselective allylation of allylic phosphonates. The products can be converted into vinylic phosphonates via two types of reactions. The first involves Cope rearrangement yielding the terminal vinylphosphonates of the 1,5-hexadiene system. The second involves γ-silanylation leading to the formation of the 1-silanyl-3-phosphono derivatives of the 2,5-hexadiene skeleton. Keywords: allylic and vinylic phosphonates, nucleophilicity of allylphosphonate carbanions, electrophilic silanylation, Cope rearrangement of alkenylphospho

Abstract:

Reaction of diethylamine with 3-chlorononafluoro-1,5-hexadieae (I) in molar ratio of 1.5 : 1 to 2 : 1 at -30 to -17 °C gives N,N-diethyl-1,1,2,3,4,4,5,6,6-nonafluoro-2,5-hexadienylamine (II) which is easily hydrolyzed to N,N-diethyl-2,3,4,4,5,6,6-heptafluoro-2,5-hexadienamide (III). The same reaction with the molar ratio 4 : 1 at 0-6 °C and at 40 °C produces a mixture of N,N,N',N'-tetraethyl-1,1,2,3,4,5,6,6-octafluoro-2,4-hexadiene-1,6-diamine (IV), N,N,N',N'-tetraethyl-1,1,2,3,4,4,5,6,6-nonafluoro-2-hexene-1,6-diamine (V), and N,N,N',N'-tetraethyl-1,2,3,3,4,5,6,6-octafluoro-1,4-hexadiene-1,6-

3-Chlorononafluoro-1,5-hexadiene (I) is isomerized into 6-chlorononafluoro-1,4-hexadiene (II) by action of basic catalysts as sodium cyanide in anhydrous dimethylformamide, lithium chloride in dimethylformamide, and triethylamine in dioxane or dimethylformamide.

Abstract:

The structure of the compounds formed upon reacting Fe(Pri2P(CH2)nPPri2)Cl2 (n = 1-3) and active-Mg with acyclic and cyclic 1,3-, 1,4- and 1,5-dienes depends upon the nature of the diene and upon the length of the methylene-chain bridging the two P-atoms of the bidentate ligand. For example, isoprene reacts to give either (η4-isoprene)2FePPri2C2H4PPri2 or (η4-isoprene)Fe(Pri2PC3H6PPri2) while the products of the reaction with 1,5-hexadiene are (η5-1-methylpentadienyl)Fe(Pri2PC2H4PPri2)H or (η2,η2-1,5-hexadiene)Fe(Pri2PC3H6PPri2).

Abstract:

Irradiation, through Pyrex, of an acetonitrile–methanol (3:1) solution of 1,4-dicyanobenzene (1) and 1,5-hexadiene (9) leads to formation of ortho and meta cyclic adducts (13–16) arising from the intermediate exciplex. There was no evidence for interaction between the two double bonds of this nonconjugated diene. The oxidation potential of 9 is high enough (> 3 V vs. sce) to preclude single electron transfer (SET); no photo-NOCAS products are formed. Similar irradiation of acetonitrile–methanol solutions of 1 and 2-methyl-1,5-hexadiene (10) does yield a photo-NOCAS product (17); reaction oc

Abstract:

The competitive catalytic hydrogenations of pairs of 2,5-dimethyl-2,4-hexadiene with 1-heptene and 2-octyne with 1-heptene were studied on palladium black modified with lead or thallium to various degrees of coverage. The dissolved and adsorbed hydrogen was determined electrochemically and the selectivities of the competitive hydrogenations were established. The effect of the lead or thallium ad-atoms on the hydrogenation kinetics is discussed.

Abstract:

Diozonolyses in methanol of (E)-4-chloro-2,3-dimethyl-1,3-hexadiene (4a) and of (4E)-5-chloro-3,4-dimethyl-2,4-heptadiene (4b) resulted in complete cleavage of the double bonds and of the single bonds of the respective diene systems. The course of these anomalous cleavage reactions has been established by step-wise ozonolyses of these dienes, and by the identification of labile methoxy hydroperoxides as intermediates.

Abstract:

In this note we report the synthesis of a doubly acylated cis-THF-diol product synthesised in three steps by the stereoselective RuO4-catalysed oxidative cyclisation of 1,5-hexadiene, followed by benzoylation and acetylation. This substance is one of the substrates chosen to probe a new developed oxidative procedure to transform bis-acylated THF-diols into bis-acylated 1,4-diketones. This new derivative was fully characterised by spectroscopic methods.

Abstract:

The predictive use of scaled minimal basis sets calculations of electric polarizabilities for large hydrocarbons, proposed by Chablo and Hinchliffe, is further assessed by considering two series of oligomers, H—(CH=CH)n—H and H—(C≡C)n—H where n = 1, 2, 3, and 4. It is then applied to the yet experimentally untested vinylacetylene, 1,5-hexadiene-3-yne, and 1,5,9-decatriene-3,7-diyne for their polarizability.

Abstract:

Mass spectrometric measurement of the pyrolyzed (790-1 030 K) mixture of 1,5-hexadiene or 2,5-dimethyl-1,5-hexadiene with dioxygen afforded no evidence for the presence of allylic peroxyl radicals or aldehydes in the gas phase though the allylic radicals were readily detected at low ionization potentials. On the other side, the electron spin resonance measurement revealed that the allylic radicals were converted quantitatively to allylic peroxyl radicals during condensation of pyrolytic mixtures at 77 K, and acrolein and methacrolein were found mass spectrometrically after thawing of the conde

Abstract:

A simple method for the two-stage synthesis in one reactor on one catalyst of heterophase thermoplasticelastomers based on isotactic polypropylene (PP) and an ethylene-propylene copolymer or an ethylene-propylene-1,4-hexadiene terpolymer is developed. The obtained materials, depending on the composition,have good elastomeric properties or behave like thermoplastics. Polymers in which ethylene units formlong sequences have the best set of basic characteristics: high values of the elastic modulus, strength, andelongation at a break, as well as a low residual deformation.
