[摘要]:Hiterto unsuccessful cross-couplings of ortho-substituted or thioether-substituted methylphenylboronates have now been achieved, under microwave conditions, enabling the synthesis of a library of novel biaryls. Tetrakis(triphenylphosphine) palladium and various bases, for example, sodium carbonate or cesium fluoride, were found to mediate the crucial C-C bond-forming cross-coupling reaction. |
