Synthesis of brominated bisamides and their application to the suzuki coupling
Two brominated bisamides were developed by this protocol. Compounds were synthesized either by 4-bromobenzoyl chloride and ethylenediamine or by ortho-phenylenediamine. The choice of the diamine led to the desired products, which were characterized by IR, H-1 NMR, C-13 NMR and XRD techniques. Compounds were applied to the Suzuki coupling. They were efficient for bromides with activating and deactivating substituent groups. In the reaction performed at low temperature and in short time, with yields over 95%, it was fundamental to choose the palladium source. (C) 2018 Published by Elsevier B.V.
