Abstract
The platinum(0) complexes [Pt(C2H4)(PP)] (PP = 1,2‐bis[(diphenylphosphino)methyl]benzene (2) and (+)‐DIOP = (+)‐1,4‐bis(diphenylphosphino)‐1,4‐dideoxy‐2,3‐O‐isopropyliden‐D‐threitol), when promoted by CH3SO3H, become active catalysts for styrene hydroformylation with total yields of aldehydes ranging from 44 to 67% und selectivities towards 3‐phenylpropanal ranging from 80 to 88%. Smaller amounts of the corresponding alcohols (3–18%) are also obtained with a selectivity towards 3‐phenylpropanol of 94–96%. When DIOP complexes were used, no stereoselectivity for asymmetric hydroformylation was observed. Copyright © 1990 Verlag GmbH & Co. KGaA, Weinheim
