HCID 7794Citronellal

Procedure

The complexes derived from Rh4 (CO)12 or Rh6 (CO)16 and from 1,2-bis-(diarylphosphinomethyl)-cyclobutanes are very particularly suitable for the asymmetric hydrogenation of neral and geranial to give enantiomers of citronellal, because they simultaneously provide a high hydrogenation rate, a good selectivity with respect to citronellal and a good optical purity.
