Intermolecular C−N Addition of Amides and S−N Addition of Sulfinamides to Arynes
摘要:
An efficient, mild, transition-metal-free method has been developed for the intermolecular C-N sigma-bond addition of amides and S-N sigma-bond addition of sulfinamides to arynes to form one C-C bond and one heteroatom-carbon bond in one step at room temperature. Evidence for a stepwise mechanism is provided.

The solution of sodium trifluoromethanesulfinate (sodium “triflinate”) and phosphoryl chloride (), in AcOEt, behaves like an equivalent of the CF3S(O)+ cation. It can be used in situ to prepare trifluoromethanesulfinates (CF3S(O)OR) or trifluoromethanesulfinamides (CF3S(O)NHR) at room temperature from alcohols or amines, respectively.
