Reactions of carbonyl compounds with tervalent phosphorus reagents. Part 7. Benzaldehyde with chlorodiphenylphosphine in the presence of acetic acid
Abstract
The reaction of chlorodiphenylphosphine (1a) with benzaldehyde in the presence of acetic acid has been re-examined. The final products have been isolated and identified as α-acetoxybenzyldiphenylphosphine oxide (4) and bis-α-(diphenylphosphinoyl)benzyl ether (5). The relative amounts of (4) and (5) formed are markedly influenced by the proportion of aldehyde in the reaction mixture.
