Abstract
The cationic Rh(I) dicarbonyl complex [{Rh((mim)(2)CH2)(CO)(2)}+BPh4-] (1), containing a bidentate bisimidazolylmethane ligand [mim = N-methylimidazol -2-yl], acts as an efficient catalyst for the intramolecular hydroamination of both terminal and nonterminal alkynes. The complex catalyzes the regios elective formation of nitrogen-containing heterocycles from aliphatic amino alkynes and the cyclization of o-alkynylanilines to 2-substituted indoles i n high yield.
