The methylene-bridged Rh(1) dicarbonyl complex, [Rh(bim)(CO)(2) BPh4 (1) (bim = bis(N-methylimidazol-2-yl)methane), is an effective catalyst for the intramolecular hydroamination of selected ortho-alkynylanilines to give a range of benzo(dipyrroles). (C) 2009 Elsevier Ltd. All rights reserved.

The cationic Rh(I) dicarbonyl complex [Rh(bim)(CO)2}+BPh4–] 1, containing a bidentate bisimidazolylmethane ligand [bim refers to bis(N-methylimidazol-2-yl)methane] acts as a catalyst for the cyclization of alkynyl amides to produce lactams and N-acyl heterocyclic compounds.
