Rhodium carbonyl catalysts, immobilized on polymeric supportes in the hydroformylation of olefins

s The hydroformylation of olefins in presence catalytic systems on a basis RhCl3*3H2O and a copolymer of styrene with 4-N-pyrrolidinopyridine units in a main chain and acacRh(CO)2 and polymeric organosiloxanes was investigated. These catalytic systems have high stability and activity. The hydroformylation of isobutylene in the presence of such systems proceeds with high speed in conditions, when traditional homogeneous catalysts unactivity. It was showed by ESCA, that complexing of rhodium with pyrrolidinopyridine units of copolymer occurs on atom of nitrogen of pyridine ring. The influence of composition and structure of polymeric supports on creation of active centers of catalysts and their catalytic properties was investigated. The influence of solvents on catalytic properties of polymeric catalysts was studied.
