Triphenylphosphine → 12-Methyl-11-tridecenyl-triphenylphosphonium Bromide

Participants

Reaction Steps

1-Bromo-12-methyl-11-tridecene (4.4 g, 16 mmoles) and triphenylphosphine (4.65 g, 17 mmoles) dissolved in acetonitrile (80 ml) were heated to reflux for 4 days, cooled and concentrated in vacuo. The residue was chromatographed on silica gel eluted with chloroform and then with methanol-chloroform (2:3). Fractions containing the product were concentrated in vacuo, triturated with ether, filtered and dried in vacuo to afford the desired phosphonium salt.
