Alkenes react with carbon monoxide, sodium borohydride, propan-2-ol and a catalytic amount of Rh(cod)(η6-PhBPh3)(cod = cyclooctadiene) to give alcohols in fine yields; high regioselectivity for the branched or linear alcohol is usually observed, depending on the organic substrate.
We report herein on an accessible protocol for the asymmetric hydroformylation of vinylarenes usingformaldehyde as a substitute for syngas. The regioselectivity (branched/linear = up to 96/4) and enantioselectivity (up to 95% ee) can be attributed to the use of chiral Ph-bpe as a ligand.

A process for the hydrogenation of a substrate comprising a carbon heteroatom double bond in the presence of a transition metal complex comprising a tridentate or bisdentate- ligand containing a nitrogen, sulphur and phosphorus atom, of which at least the N- and P- and optionally also the S-atom coordinates with the transition metal.
