Hydroformxlation of olefins catalyzed by Rhodium complex anchored on clay matrices

Abstract

Investigations on the catalytic activity of a transient Rh(I) triphenylphosphine complex ! anchored on montmorillonite clay have been carried out with respect to hydroformylation of olefins at 70 ~ and 60 atm of CO+H2(1:1). The analysis has shown that aldehydes and hydrocarbons of the corresponding olefins result under hydroformylation conditions. In limonene, reaction proceeds with double hydroformylation and hydrogenation to give the respective oxo products. The catalytic activities of ! are compared with Wilkinson's RhI(H) (CO) (PPh3)2(6) complex in solution under the same hydroformylation conditions.
