process for the production of chlorotris (triphenylphosphane) rhodium (i)

摘要

A process is described for the manufacture of chlorotris(triphenylphosphine)-rhodium(1) by means of causing a reaction of RhClSUB3 /SUBsolution with triphenylphosphin in mixtures of C2-C5 alcohols with water subsequently cooling down and filtering the crystalline precipitate obtained characterized in that the mixture of the reactants is handled in such a way that B is warmed up to 75° C., and C is maintained at 80 to 110° C. The technique leads to improvements in the yield and quality of the crystals obtained.
