Reaction Steps
To a solution of triphenylphosphine (25.92 g) in 300 mL CH2Cl2 is added 4-nitrobenzylbromide (31.47 g). The solution is allowed to stir overnight. The mixture is concentrated. The resulting solid is triturated with Et2O, filtered and dried to yield 54.58 g (95%) of (4-nitrobenzyl)(triphenyl)phosphonium bromide as a white solid.
