ABSTRACT:
Novel compositions and novel hydroformylation catalysts are prepared by the interaction of an organorhodium halide of the formula (L).sub.n Rh(X).sub.m, wherein X is chlorine, bromine or iodine, L is a cyclic diene or a cyclic triene, n equals 1 or 2, m equals 1 or 2, the sum of n + m equals 2 or 3; hydrazine or a hydride of Group IA, IIA or IIIA metals; and a phosphorus containing adjuvant of the formula L'.sub.3 P, wherein each L' individually represents aryl, aryloxy, alkaryl, aralkyl, alkaryloxy, aralkoxy, alkyl or alkoxy radicals. The hydroformylation catalysts promote the conversion of olefins to linear aldehydes.
