실험 절차

A solution of iodomethylcyclopentane (129.38 g, 0.616 mol) and triphenylphosphine (161.54 g, 0.616 mol) in acetonitrile (308 mL) was heated under reflux for 9 d. The reaction mixture was allowed to cool to 25° C. and then concentrated in vacuo to provide a solid. The solid was triturated with diethyl ether and then filtered. The solid was washed well with diethyl ether until the washings showed the absence of iodomethylcyclopentane and triphenylphosphine by thin layer chromatography. The resulting solid was allowed to air dry to afford cyclopentylmethyl triphenylphosphonium iodide (266.92 g, 92%) as a light yellow solid: mp 195-198° C.; FAB-HRMS m/e calcd for C24H26P (M+H)+345.1772, found 345.1784.
