HYDROFORMYLATION OF OLEFINS CATALYZED BY RHODIUM COMPLEX ANCHORED ON CLAY MATRICES

Investigations on the catalytic activity of a transient Rh(I) tripheny lphosphine complex 1 anchored on montmorillonite clay have been carrie d out with respect to hydroformylation of olefins at 70-degrees-C and 60 atm of CO+H-2 (1:1). The analysis has shown that aldehydes and hydr ocarbons of the corresponding olefins result under hydroformylation co nditions. In limonene, reaction proceeds with double hydroformylation and hydrogenation to give the respective oxo products. The catalytic a ctivities of 1 are compared with Wilkinson's Rh(I) (H)(CO)(PPh3)2 (6) complex in solution under the same hydroformylation conditions.
