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)
在二茂钛 (II) 试剂 Cp2Ti[P(OEt)3]2 存在下,新戊酸乙烯酯与非极性 C≡C 三键和极性 C=O 双键反应,分别生成共轭二烯和烯丙醇。当 (Z)-烯基砜用炔烃和羰基化合物处理时,也会发生类似的烯基化反应。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
