Vinyl pivalate in the presence of the titanocene( II ) reagent Cp 2 Ti[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)
