The reaction of organotitanium species prepared by the desulfurizative titanation of thioacetals with (C5H5)2Ti[P(OEt)3]2 in the presence of trialkyl(allyl)silanes gives γ-substituted allylsilanes with Z stereoselectivity.
在三烷基(烯丙基)硅烷存在下,通过硫代乙酸酯与 (C5H5)2Ti[P(OEt)3]2 的脱硫钛化反应制备的有机钛,可以得到 Z 立体选择性的δ-取代烯丙基硅烷。
