Triphenylphosphine → ((4'-Chlorobiphenyl-2-yl)methyl)triphenylphosphonium iodide

Participants

Reaction Steps

To a solution of 4′-chloro-2-(iodomethyl)biphenyl in toluene (11 mL), triphenylphosphine (1.20 g, 4.57 mmol) was added. The result mixture was refluxed overnight, allowed to cool to room temperature and filtered. The solid was washed with ether and dried under vacuum to afford ((4′-Chlorobiphenyl-2-yl)methyl)triphenylphosphonium iodide (2.50 g, 93%): 1H NMR (400 MHz, chloroform-d) δ ppm 6.35-8.06 (m, 23 H), 5.12-5.63 (m, 2 H).
