The cathodic electrolysis of aliphatic alcohols and alkylphosphonates in acetonitrile with 0.5 N Et4NClO4 as the base electrolyte leads to mono- and ditransesterified phosphonates. The yield and ratio of these products is a function of the nature of the starting reagents and amount of current passed.

This invention provides chlorohydrocarbyloxy phosphonate oligomers, organophosphonate oligomers, and processes for the preparation of such oligomers. The chlorohydrocarbyloxy phosphonate oligomers can be represented by the formula (IV) where R1 is a linear or branched hydrocarbylene group or oxygen-containing hydrocarbylene group, which hydrocarbylene group has about two to about twenty carbon atoms, or a hydrocarbylene group having at least one cycloaliphatic or aromatic ring; R2 is an alkyl group or an aromatic group; and n is a number from about 2 to about 20.
