Abstract
Some palladium carbonyl clusters containing the palladium in the (+1) formal oxidation state, and derivatives of these clusters investigated in our laboratories are examined in this paper. In particular, letranuclear carbonyl carboxylates of palladium are discussed as a model of key intermediates in various processes, including CO oxidation by a palladium catalyst with molecular oxygen as the oxidant. A second type of cluster, a palladium cationic cluster which contains N-donor ligands acts as a catalyst precursor for processes such as exhaust gas purification. A third type of palladium carbonyl cluster includes bimetallic compounds which catalyse new reactions, such as the low-temperature dehydration of alcohols.
