Abstract

A boryl-Heck reaction of terminal alkenes with commercially available catecholchloroborane (catBCl) as an electrophilic boron reagent provides trans-alkenyl boronic esters. In situ transesterification allows for rapid access to various boronic esters, amides, and other alkenyl boron adducts.
