Oxidising alcohol to their corresponding carbonyl compound is still a vitally important reaction for the fine chemical and pharmaceutical industries. In this thesis the investigation of the use of Pd(II) catalysts for the oxidation of alcohols using 02 as the terminal oxidant is reported. The initial section describes the investigation of ligand effects on Pd(OAc)2 operating under homogeneous conditions. The examination into the use of different gas mixtures showed that 02/C02 was beneficial due to the formation in situ of alkylcarbonic add by the reaction between C02 and the alcohol substrate. The heterogenisation of Pd(II) catalysts and an efficient silica adsorbed Pd catalytic system is also considered. Compared with previous homogeneous catalysts, the new Pd systems show encouraging activity on a silica support. As a development of this, more stable and durable Pd catalysts have been prepared using several different kinds of covalent tether to silica and tested for the Pd catalyzed aerobic alcohol oxidation.
