Abstract
Usually the Rh-catalyzed hydroformylation of styrene predominantly yields the branched, chiral aldehyde.
An inversion of regioselectivity can be achieved using strong π-acceptor ligands. Binaphthol-based
diphosphite and bis(dipyrrolyl-phosphorodiamidite) ligands were applied in the Rh-catalyzed hydroformylation
of styrene. High selectivities up to 83% of 3-phenylpropanal were obtained with 1,1-bi-
2-naphthol-based bis(dipyrrolyl-phosphorodiamidite) with virtually no hydrogenation to ethyl benzene.
The coordination chemistry of those ligands towards Rh(I) was investigated spectroscopically and
structurally.
