Accelerated Heck reaction using ortho-palladated complex in a nonaqueous ionic liquid with controlled microwave heating

Abstract

The activity of {Pd[C6H2(CH2CH 2NH2)-(OMe)2,3,4] (μ-Br)}2 complex was investigated in the Heck-Mizoroki C-C cross-coupling reaction under conventional heating and microwave irradiation conditions in molten salt tetrabutylammonium bromide as the solvent and promoter at 130 °C. This complex in these conditions is an active and efficient catalyst for the Heck reaction of aryl iodides, bromides and even chlorides, and also arenesulfonyl chlorides.
