Abstract
Branched alkyl diaryl phosphine rhodium carbonyl hydride complexes are surprisingly effective, stable and selective hydroformylation catalysts particularly in the presence of a large excess of t-phosphine ligands. As such, they are advantageously employed as catalysts in a novel low pressure rhodium hydroformylation process producing normal and iso aldehydes by reacting olefins with H.sub.2 and CO.
