Vinyl pivalate in the presence of the titanocene(II) reagent Cp2Ti[P(OEt)3]2 reacts both with nonpolar C≡C triple bonds and with polar C=O double bonds, to produce conjugated dienes and allylic alcohols, respectively. Similar alkenylation also takes place when (Z)-alkenyl sulfones are treated with alkynes and carbonyl compounds. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
