Patent ID: 7297813

Claim:
A method of removing RSO 2 OR′ from a composition, the method comprising contacting the composition with a reagent selected to convert the R′ moiety or the OR′ moiety of the RSO 2 OR′ to one or more products selected from the group consisting of R′X, R′SO 3 H, R′SO 3 M n , R′SO 3 − R″R′″ R″″NH + , R′SO 3 R″, R″-ZOR′, (HO) 2 PO(OR′), HOPO(OR′) 2 , (R′O) 3 PO, (M n O) 2 PO(OR′), HO 3 S—R″-ZOR′, M n O 3 S—R″-ZOR′, M n O 3 S—R″(ZOM n )-ZOR′, oxidized carbon species, and water, thereby converting the RSO 2 OR′ to RSO 3 H; wherein R and R′ are each independently a C 1 -C 20 alkyl, aralkyl or alkenyl group, or any of these incorporating a substituent selected from the group consisting of halogens and functional groups comprising oxygen, sulfur, silicon, tin, phosphorus, or nitrogen; R″ is a polymeric group or a C 1 -C 20 alkyl, aryl, aralkyl or alkenyl group, or any of these incorporating a substituent selected from the group consisting of halogens and functional groups comprising oxygen, sulfur, silicon, tin, phosphorus, or nitrogen; R′″ and R″″ are independently a polymeric group, hydrogen or a C 1 -C 20 alkyl, aryl, aralkyl or alkenyl group, or any of these incorporating a substituent selected from the group consisting of halogens and functional groups comprising oxygen, sulfur, silicon, tin, phosphorus, or nitrogen; M is a metal selected from the group consisting of Group I metals, Group II metals, transition metals, Al, Sn, Sb, Pb, and Bi, provided that M is a Group I or Group II metal when the product is (M n O) 2 PO(OR′), M n OPO(OR′) 2 or M n O 3 S—R″(ZOM n )-ZOR′; n is equal to the reciprocal of the oxidation state of the metal; Z is CO, P(O)OH, P(O)OR″, or S(O); and X is halogen.
