Abstract

Manganese(Ill) acetate (Mn(OAc)(3))-mediated synthesis of biaryls and heterobiaryls starting from arylboronic acid was developed under microwave irradiation in high yields Microwaves were also used for the synthesis of Mn(OAc)(3) from KMnO4 and acetic acid Additional irradiation of this in situ generated Mn(OAc)3 with arylboronic acids, which in turn furnished the biaryls in high yields In a one pot reaction This IS superior from the point of view of yield, short reaction time, sensitive functional group toleration, and more environmentally friendly than the reported methods with a minimum amount of benzene and thiophene as a reagent but not as a solvent (C) 2009 Elsevier Ltd All rights reserved
