Synthesis of 1-alkenylboronic esters via palladium-catalyzed cross-coupling reaction of bis(pinacolato)diboron with 1-alkenyl halides and triflates
The synthesis of 1-alkenylboronic acid pinacol esters via the palladium-catalyzed cross-coupling reaction of I-alkenyl halides or triflates with bis(pinacolato)diboron [(Me4C2O2)B-B(O2C2 Me-4)] was carried out in toluene at 50 degrees C in the presence of potassium phenoxide (1.5 equivalents) and PdCl2(PPh3)(2). 2PPh(3) (3 mol%).
