Structure and catalytic activity of metal complexes immobilized on supports. Part 1. The synthesis of palladium complexes on silica gel, modified by aldiminopropylheteryl groups, and their properties
Based on silica gel containing a ..gamma..-aminopropyl group and ..cap alpha..-, ..beta..-, and ..gamma..-aldehydes of the heterocyclic series, supports having graft aldimine groups and their stable complexes with palladium have been obtained. It has been established by IR spectroscopy that the hydroxyl coating of silica gel is almost completely replaced by functional groups of ligands combined with the surface through O atoms. The Pd atom is coordinated by the N atom of the aldimine group, the heteroatom of the pyridine ring, and in the case of furan by the ..pi..-electrons of the ring. The catalytic activity and selectivity of Pd complexes in the isomerization and hydrogenation of allylbenzene is determined by the nature of the grafted heterocyclic ligand.
