Abstract

We present herein a high yield, highly selective catalytic synthesis of vinylboronate esters (VBEs), including 1, 1-disubstituted VBEs, from alkenes without significant hydrogenation or hydroboration, using the simple catalyst precursor, trans-[RhCl (CO)(PPh3) 2](1), and the diboron reagents B2pin2 (2a, pin= pinacolato= OCMe2CMe2O) or B2neop2 (2b, neop= neopentylglycolato= OCH2CMe2CH2O), or the monoboron reagent HBpin, all of which ...
