Procedure

A mixture of 60 parts by volume of DMF, 6.4 parts of 2-picolyl chloride and 13.2 parts of triphenylphosphine is stirred at 100° C. under nitrogen for 4 hours. The crystals which have precipitated are filtered off with suction, washed with petroleum ether and dried. 12 parts=59% of theory of triphenyl-2-picolylphosphonium chloride are obtained.
