ChemInform Abstract: A One-Pot Synthesis of (E,E)-1-Arylseleno-Substituted 1,5-Dien-3-ynes by Palladium-Catalyzed Three Component Cross-Coupling Reaction.
Under very mild conditions, functionalized benzoxaborole derivatives were prepared in good to excellent yields via a palladium-catalyzed Miyaura borylation reaction of readily available unprotected o-bromobenzylalcohols, and bis(pinacolato)diboron (B2pin2) without the assistance of an acid.
