Procedure

An amount of 9.1 grams (37 mmol) of 1-chloro-3,7,11-trimethyl-dodeca-2,6-diene and 9.8 grams (37 mmol) of triphenyl phosphine were heated to boiling in 30 ml of toluene for a period of five hours. The resultant suspension was mixed with 200 ml of hexane and after precipitation of the white solid material, the liquid was decanted. This mixing with hexane was repeated five times and the remaining tacky solid substance was dried under reduced pressure. An amount of 18.2 grams (3,7,11)-trimethyl-dodeca-2,6,10-trien-1-yl)triphenylphosphonium chloride (E/Z isomer mixture) was obtained. The yield was 87 percent of theory.
