Abstract
TiCl(4) and TiBr(4) rapidly transform cyclopropenylmethyl acetates to (E)-halodienes via ring-opening to allyl-vinyl cations. DFT calculations suggest that the regioselectivity of the halogenation of this cationic intermediate by [TiX(4)OAc](-) is under thermodynamic control, while the stereoselectivity is governed by kinetics.
