Abstract
The mechanism of the formation and the nature of microheterogeneous catalysts for hydrogenation are discussed using acetylacetonate complexes of palladium with phosphine ligands as an example. Polynuclear palladium complexes with phosphide and phosphinidene ligands are obtained, and their role in the formation of hydrogenation catalysts is found. As distinct from phosphide complexes, amide complexes of palladium are unstable in a hydrogen atmosphere and undergo reduction to form highly dispersed palladium black.
