A (1:1) molar complex of triphenyl phosphine and rhodium trichloride was prepared as catalyst by suspending finely ground rhodium trichloride trihydrate (2.0 g.) and triphenyl phosphine (12 g.) in methanol (40 ml.) and stirring the mixture at room temperature for 90 minutes, after which the formed brown precipitate of the complex was filtered off and washed with ethanol (50 ml.) and diethyl ether (50 ml.) to remove unchanged reactants; no further purification was necessary.
