ChemInform Abstract: One-Pot Synthesis of Highly Substituted Polyheteroaromatic Compounds by Rhodium(III)-Catalyzed Multiple C-H Activation and Annulation.

Rh-catalyzed reaction of N-hydroxybenzamidines with an excess of internal alkynes and an excess of Cu(OAc)2 as the oxidant is described to produce polyhetarenes in good yields. [ABSTRACT FROM AUTHOR]
