En el capítulo I, se ha llevado a cabo el acoplamiento oxidativo de aminas mediado por un catalizador de hierro, para la preparación de tioamidas, de forma eficiente y selectiva en una reacción multicomponente. En la misma, se han utilizado dos aminas diferentes, fosfato de sodio y azufre elemental, bajo calentamiento por microondas.

Abstract:

Several chelating phosphine-imidazolium salts have been synthesised and their activity tested in the hydrosilylation of styrene with triethylsilane and the Heck coupling of aryl bromides and chlorides with butyl acrylates. A number of synthetic routes have been established to synthesise aryl substituted phosphine-imidazolium salts. New synthetic routes have been established to synthesise borane-protected alkyl substituted phosphine-imidazolium salts. These methodologies have increased the scope to synthesise new alkyl substituted phosphine-imidazolium salts. Several group 9 and 10 complexes of

Abstract:

N-heterocyclic carbenes (NHCs) have been developed in the last two decades as an important material in homogenous catalysis. Also MOFs have recently been receiving a great deal of attention due to their potential applications e.g. gas storage, adsorption and catalysis. This study involved the synthesis of new imidazolium salt functionalised with nitriles, carboxylates and pyridyl and their conversion into NHC complexes and porous coordination polymers. A series of nitrile substituted imidazolium salts were synthesised. 1,1-bis(4-cyanophenyl)-3,3-methylenediimidazolium and 1-bromomethyl-3-(4-cy

碩士<br>高雄師範大學<br>化學系<br>97<br>The aim of this work is to use unsymmetrical imidazolium and benzimidazolium salts containing hexanoic acid (C5H10COOH) functionalized cations to synthesize bisphenol A functionalized imidazolium and benzimidazolium salts with anions of Br-, BF4-, and ZnBr42- . The properties of these compounds were investigated by polar optical microscope, differential scanning calormetry, and powder X-Ray diffractometer. The results exhibited that anion species played an important role on the liquid crystalline properties of the imidazolium and benzimidazolium salts. The poss

博士<br>國立東華大學<br>化學系<br>105<br>This thesis comprises four parts. The first part describes the synthesis of fan shape Alkoxy benzyl and aryl functionalized imidazolium salt. The liquid crystal behavior and self-assembly property were discussed. In the second part, the liquid crystalline gold nanoparticles were prepared. To synthesize AuNPs via modified the Schiffrin’s two-phase method with imidazolium salt without additional stabilizing agent is reported. These AuNPs show good thermal ability and liquid crystalline SmA behavior. The temperature dependent SPR bands are observed for these AuNPs.

The neutral ligands of N-alkylimidazole do not exhibit mesomorphic behaviour. However, liquid crystalline products may be obtained upon protonation, alkylation and metalation. After protonation, compounds with various anions of [NO3-], [BF4-], tartrate annd Cl- exhibits SmA mesophase.

碩士<br>輔仁大學<br>化學系<br>88<br>The aim of our work is to synthesize and investigate liquid crystalline properties of N,N-dialkyl imidazolium derivatives (IM(OH)R2Br, n=10, 12, 14, 16, 18), N,N,O-trialkyl imidazolium (IMOR3Br, n=12, 14, 16, 18) and oligoethylene glycol substituted imidazolium salt. Because N,N,O-trialkyl imidazolium salts have hydroxyl group near the rigid part, we can compare these results with our previously reported simple N,N-dialkylimidazolium salts. Liquid crystalline behaviors of these compounds were investigated by differential scanning calorimetry and polarized optical mic

Although a great diversity of synthetic antibacterial all have their own specific characteristics and also been used widely in recent years. However an antibacterial with broad, excellent and low-toxic behaviors is still under demand. Poly(ionic liquid)s, which is also known as a green solvent, was used for the antiseptic capability studies.
