Benzyl Bromide → (5-Bromopentyl)benzene

Participants

Reaction Steps

Phenylmethyl-triphenylphosphonium bromide (51 a) (PAA 59). Triphenylphosphine (2.364 g, 9.00 mmol) was added to benzyl bromide (1.348 g, 8.00 mmol) in 35 mL toluene in a 100-mL round-bottom flask. The mixture was heated to reflux under argon and stirred 24 h, then concentrated in vacuo. The resulting white amorphous solid was triturated with ether (3×20 mL) to yield 3.268 g (94%) white powder. 1H NMR (CDCl3, 300 MHz) δ 7.58-7.78 (m, 15H), 7.10-7.26 (m, 5H), 5.34-5.42 (m, 2H).
