Triphenylphosphine → 3-Methoxycarbonyl-5-phenylbenzyl triphenylphosphonium bromide

Participants

Reaction Steps

A solution of methyl 3-bromomethyl-5-phenylbenzoate (3.78 g; 1.23 mmol) and triphenyl phosphine (3.26 g; 1.23 mmol) in toluene (40 ml) was heated at reflux under argon atmosphere for 9 hours. The resulting solid was filtered, washed with ether and pentane to give 3-methoxycarbonyl-5-phenylbenzyl triphenylphosphonium bromide. Yield=76%.
