摘要

A convenient new method for the arylation of furan and thiophene with arylhydrazine and manganese (III) acetate is described. Oxidation of arylhydrazines with Mn (III) acetate in furan or thiophene affords the corresponding 2-aryl-substituted furans and thiophenes in good yield using commercially available materials; access to 2-substituted heterobiaryls works selectively, and coupling occurs with loss of the hydrazine moiety.
