(Et(2)N)(2)PCl. Two applications of these compounds to synthetic asymmetric organophosphorus chemistry have been examined: their reactions with 2,3,3-trimethylbutene and AlCl(3) afford either P-chiral phosphetane oxides or, in the presence of gaseous HCl, P-chiral phosphinic chlorides with moderate to high diastereoselectivity.
