Abstract
Sequential treatment of racemic phosphine oxides with oxalyl
chloride and chiral non-racemic alcohol generates the same
ratios of diastereomeric alkoxyphosphonium salts obtained in
the corresponding asymmetric Appel process, strongly implicating
the intermediate chlorophosphonium salt in the stereoselecting
step. Subsequent reduction allows a novel synthesis of enantioenriched
P-stereogenic phosphines¿phosphine boranes.
