bromination, iodination, allylation, and propargylation to generate unique vinyl boronates and vinylphosphonates not obtainable by other methods. The reaction proceeds in two steps, with both high regio- and stereoselectivity. With the vinyl boronates, the Zr−Csp2 bond is initially cleaved by 1 equiv of electrophile. With the phosphonates, either the Zr−Csp2 bond (allyl bromide, Br2) or the Zr−Csp3 bond (I2

Di- or tri-substituted vinylphosphonates, 2–5, can be obtained in a highly regio- and stereoselective manner from 1-alkynylphosphonates, by manipulation of Ti(O-i-Pr)4/2i-PrMgCl.
