  • Suzuki-Miyaura Cross-Coupling Reaction | TCI AMERICA

    Suzuki-Miyaura reaction is a palladium catalyzed cross-coupling reaction between organic boron compounds and organic halides. 1) The reaction requires an additional base for the activation of the boron compound and proceeds under mild conditions. This relatively simple and versatile C-C bond formation reaction can be extended to various substrates and therefore finds wide application for the …
