Method for producing chlorotris(triphenylphosphine) rhodium (i)

摘要

A process is described for the manufacture of chlorotris(triphenylphosphine)-rhodium(1) by means of causing a reaction of RhCl₃ solution 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.
