The present invention describes a method for stereospecific isomerisation of prochiral allylamines into enamines and chiral imines, by using catalysts of Rh, Ir and Ru having phosphine chiral ligands immobilised on a solid material. The immobilised ligands are derivatives of phosphines of the type bis(diphenylphosphino)biaryl such as, for example, the phosphine known by the name BINAP. The method is particularly suitable for the production of optically active citronellal which may be obtained in optical purities above 95%.
