The reactions of trichloro(2-ethoxyethenyl)phosphonium and trichloro(styryl)phosphonium hexachlorophosphorates with triethylamine were studied by 1H, 13C, and 31P NMR spectroscopy. It was shown that phosphonyl chlorides are the primary products of the reactions. The presence of the alkoxy group in hexachlorophosphorate results in the oxidation of the PCl2 group to form phosphonyl chlorides. Diphosphorylated oxaphosphinines were synthesized.

amines containing at least two ethyl groups at the nitrogen atom with phosphorus pentachloride was studied. New C-chlorophosphorylated enamines were characterized by NMR spectroscopy. A scheme was suggested for the phosphorylation reaction. It was found that the presence of two aryl substituents in the molecule of tertiary ethylamine deactivated the ethyl group to block phosphorylation. Phosphorylation
