Abstract

Official abstract text for this publication.

A method for producing a sulfoxide derivative represented by general formula (1), the method being characterized in that a sulfide derivative represented by general formula (2) is reacted with an oxidizing agent in the presence of a catalyst that is a metal-ligand complex containing a metal compound and, as a ligand, a compound represented by general formula (3), and in the presence of a benzoic acid compound represented by general formula (4)

First claim

The method according to claim 1 , wherein R 1 is a C1 to C10 alkyl group, a C3 to C6 cycloalkyl C1 to C6 alkyl group, wherein the said C3 to C6 cycloalkyl group moiety may be monosubstituted or polysubstituted by a halogen atom or a C1 to C4 alkyl group, a phenyl C1 to C6 alkyl group, wherein the said phenyl group moiety may be monosubstituted or polysubstituted by a halogen atom or a C1 to C4 alkyl group, a C1 to C4 alkoxy C2 to C10 alkyl group, a C1 to C4 haloalkoxy C2 to C10 alkyl group, a C1 to C4 alkylthio C2 to C10 alkyl group, a C1 to C4 alkylsulfinyl C2 to C10 alkyl group, a C1 to C4 alkylsulfonyl C2 to C10 alkyl group, a C1 to C4 haloalkylthio C2 to C10 alkyl group, a C1 to C4 haloalkylsulfinyl C2 to C10 alkyl group, a C1 to C4 haloalkylsulfonyl C2 to C10 alkyl group, a C1 to C6 haloalkyl group, a C3 to C6 cycloalkyl C1 to C6 haloalkyl group, wherein the said C3 to C6 cycloalkyl group moiety may be monosubstituted or polysubstituted by a halogen atom or a C1 to C4 alkyl group, or a phenyl C1 to C6 haloalkyl group, wherein the said phenyl group moiety may be monosubstituted or polysubstituted by a halogen atom or a C1 to C4 alkyl group. 3. The method according to claim 1 , wherein R 1 is a C1 to C10 alkyl group, a C1 to C4 alkoxy C2 to C10 alkyl group, a C1 to C4 haloalkoxy C2 to C10 alkyl group, a C1 to C4 alkylthio C2 to C10 alkyl group, a C1 to C4 alkylsulfinyl C2 to C10 alkyl group, a C1 to C4 alkylsulfonyl C2 to C10 alkyl group, a C1 to C4 haloalkylthio C2 to C10 alkyl group, a C1 to C4 haloalkylsulfinyl C2 to C10 alkyl group, a C1 to C4 haloalkylsulfonyl C2 to C10 alkyl group, or a C1-C6 haloalkyl group. 4. The method according to claim 1 , wherein R 1 is a C1 to C4 haloalkylthio C2 to C10 alkyl group; and R 2 and R 3 are each independently a halogen atom or a C1 to C4 alkyl group. 5. The method according to claim 1 , wherein R 1 is a 5-trifluoromethylthiopentyl group or a 6-trifluoromethylthiohexyl group; and either R 2 is a fluorine atom and R 3 is a chlorine atom, or R 2 and R 3 are methyl groups. 6.
