Patent ID: 8097747

Claim:
A process for alkylating a phosphorus-containing compound to provide an alkylated phosphorus-containing compound which comprises alkylating phosphorus-containing compound possessing at least one phosphorus-hydrogen alkylatable site with reactant which generates alkene and/or cycloalkene alkylating agent in situ in the presence of initiator, the alkylene and/or cycloalkylene alkylating agent alkylating the phosphorus-containing component to provide alkylated phosphorus-containing product wherein phosphorus-containing compound is represented by general formula (I): wherein: x 1 , where present, is and x 2 , where present, is in which R 1 is H, alkyl of up to 30 carbon atoms, cycloalkyl of from 3 to 12 carbon atoms or aryl of from 6 to 20 carbon atoms; Me is a metal having a valence v of 1, 2, 3 or 4; R 2 is H, alkyl of up to 30 carbon atoms, cycloalkyl of from 3 to 12 carbon atoms or aryl of from 6 to 20 carbon atoms; and, a, b, c, d, e and f each independently is 0 or 1, provided, when a=1, c=1 and b=0, when b=1, a=0 and x 1 is not present, when f=1, d=1 and e=0, and when e=1, f=0 and x 2 is not present, and the reactant which generates alkene or cycloalkene in situ is represented by general formula (II): R 4 —X (II) wherein: R 4 is alkyl of up to 30 carbon atoms or cycloalkyl of from 3 to 12 carbon atoms; and, in which R 5 and R 6 each independently is H, alkyl of up to 30 carbon atoms, cycloalkyl of from 3 to 12 carbon atoms or aryl of from 6 to 20 carbon atoms and g is 0 or 1.
