investigation of reactions of electrophilic P(III) chlorides with aliphatic aldehydes is developed. Its essence is the removal of HCl impurity from chloride and catalytic blocking of electrophilic center of the carbonyl group. For these purposes nitrogen-containing organic bases and alkyl vinyl ethers are used. Three types of primary intermediates with the nearest P(III) environment POCl2, O2PCl, and O3P are

Structure of primary intermediates of the reaction of P(III) chlorides with aliphatic aldehydes was confirmed by their reactions with such aprotic reagents like ethylene oxide, trialkylphosphites, acetals, and trialkyl orthoformates. Principle difference in the reactions of these nucleophiles with intermediates containing active chlorine atom at P(III) and those not containing was established. The
