Reactions of the electrophilic P(III) chlorides with aliphatic aldehydes are ctalized by alkyl vinyl ethers. Two types of the primary intermediates were synthesized with environment of P(III): O 2PCl and O 3P. The stability of the primary intermediates rises with increasing of the electroacceptor properties of the substituents at P(III) and electronodonor ability of aldehyde fragment.
