摘要

Abstract 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)
