An operationally simple protocol to affect a radical addition to alkenylboronates that spontaneously undergo a [1,2]‐metalate shift is described. Overall, the reaction is a three‐component coupling of an organolithium, alkenylboronic ester, and halide which takes place with broad scope and good to excellent yields. Experimental mechanistic investigations support the formation of a boron inverse ylid
