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.

Insertion of benzene rings into the amide bond using the reactive intermediate benzyne is described. Aromatic amides undergo smooth insertion when treated with O-triflatophenyl silane benzyne precursors, producing versatile aminobenzophenone products in good to excellent yield. The process is entirely metal-free and has been exemplified on the synthesis of biologically active acridones and acridines
