or bromides and bis(pinacolato)diboron has been developed. This method tolerates various functional groups, including acetyl, methoxycarbonyl, cyano, and fluoro substituents, and affords a range of tri-substituted vinylboronates, which are highly useful intermediates for the synthesis of tetra-substituted ethenes, in high yield and regioselectivity.
