The first transition-metal-catalyzed cycloaddition of isocyanides and unactivated terminal alkynes has been realized by the discovery of silver carbonate (Ag2CO3) as a unique and robust catalyst.This protocol for silver-catalyzed reaction is highly efficient allowing a broad range of terminal and internal alkynes to react with isocyanides under base-and ligand-free conditions, regioselectively generating synthetically useful 2,3-disubstituted and 2,3,4-trisubstituted pyrroles in good to high yields.
