Abstract
The yield of C6-aldehyde in the photocatalytic system Rh2Cl2(CO)4-PMe3 passes through a maximum as the CO pressure and PMe3 concentration increase. The increase in the yield of aldehydes with increasing CO pressure is related to the increase in the carbonylation rate and to the retardation of the photodecomposition of the aldehydes. The rate of the photocatalytic carbonylation of pentane in this system is 20 times higher than in the presence of RhCl(PMe3)2(CO).
