Abstract
The present invention relates to a process for the preparation of a compound of formula (I), wherein X is —CH—, —CH—CH—, —CH—CH—CH— or —CH—CH—CH—CH—; Yis —CH—; —CH—CH— or —NH—; Yis NHRor SH; wherein Ris hydrogen, C-Calkyl or phenyl; R-and R, independently from each other, represent aliphatic or aromatic groups; Rand R, independently from each other, represent aliphatic or aromatic groups; Rand Rare each hydrogen or represent together with the carbon atoms to which they are bonded, a phenyl ring; which process comprises reacting a compound of formula II [RuCI(R)n]m (II), wherein n is 1 and m is >1 which represents a polymeric structure if Ris a molecule containing two alkene or alkyne moieties coordinating in an hapto-2 coordination mode to the metal; or n is 4 and m is 1 if Ris a nitrogen, oxygen or sulfur containing molecule in which said nitrogen, oxygen or sulfur coordinate to the metal; in the presence of an inert solvent which boiling point is from 1 12° C. to 165° C. with a compound of formula (III), wherein R, R, Yand Yare as defined under formula I, and a phosphane of formula IV RRP—X—PRR(iv), wherein R, R, R, Rand X are as defined under formula I.
