Title:
PROCESS FOR PREPARATION OF FLUORINATED SULFIDES WITH IODINE PENTAFLUORIDE
Document Type and Number:
WIPO Patent Application WO/2003/040088
Kind Code:
A1
Abstract:
A process for preparation of fluorinated sulfides, characterized by reacting a sulfide of the general formula (1) having at least one hydrogen atom with IF5 to thereby replace at least one hydrogen atom of the sulfide by a fluorine atom: (1) wherein X, X1, X2 and Y are each independently hydrogen, halogeno, alkyl, cycloalkyl, heterocycloalkyl, haloalkyl, aralkyl, aryl, alkoxy, aryloxy, aralkyloxy, alkoxycarbonyl, aryloxycarbonyl, aralkyloxycarbonyl, acyl, −CONR1R2 (wherein R1 and R2 are each independently hydrogen, alkyl, aryl, or aralkyl), alkylsulfinyl, aralkylsulfinyl, arylsulfinyl, cycloalkylsulfinyl, hetero− cycloalkylsulfinyl, alkylsulfonyl, aralkylsulfonyl, aryl− sulfonyl, cycloalkylsulfonyl, heterocycloalkylsulfonyl, a heterocyclic group, cyano, or nitro&semi R is alkyl, cycloalkyl, haloalkyl, aralkyl, aryl or a heterocyclic group&semi and n is an integer of 1 to 20.
