Patent ID: 7217814

Claim:
A method of producing a phosphitylated compound comprising the step of reacting a hydroxyl-containing compound with a phosphitylating agent in the presence of a phosphitylation activator selected from the group consisting of: (1) acid-base complexes comprising a substituted pyridine or protonated pyridine moiety of Formula II wherein R 3 , R 4 , R 5 , R 6 , and R 7 are independently hydrogen, C 1 –C 10 alkyl, C 3 –C 10 cycloalkyl, C 6 –C 10 aryl, C 7 –C 10 aralkyl, C 1 –C 10 heteroalkyl, or C 1 –C 10 heteroaryl, provided that at least one of said R 3 , R 4 , R 5 , R 6 , and R 7 is not hydrogen and R 5 is not a C 2 –C 10 alkyl; (2) zwitterionic amine complexes having pyridinyl and sulfonic acid substitutent moieties; and (3) combinations of two or more thereof.
