Fe-Catalyzed insertion of fluoromethylcarbenes generated from sulfonium salts into X–H bonds (X = Si, C, P)

Abstract

The Fe-catalyzed insertion of fluoromethylcarbenes including trifluoromethylcarbene and difluoromethylcarbene generated in situ from sulfonium salts (Ph₂S⁺CH₂CF₃⁻OTf and Ph₂S⁺CH₂CF₂H ⁻OTf) into X–H (X = Si, C and P) bonds is described. The insertion of both carbenes into the Si–H bond occurred smoothly, and trifluoromethylcarbene could also insert into C–H and P–H bonds.
