用二茂钛（II）试剂Cp2Ti[P(OEt)(3)](2)将硫缩醛、宝石二卤化物和相关的有机硫和有机卤素化合物还原钛化，制备了各种碳钛配合物。由此形成的烷基二烯、杂原子取代的亚甲基二烯、2-亚烷基二烯-、2-炔基二烯-和偏二烯-钛二烯对带有多键的有机化合物具有高活性，并用于各种有机转化，如羰基烯烃化和烯烃复分解。(c) 2007日本化学期刊论坛和Wiley期刊公司。
Various titanium carbene complexes are prepared by the reductive titanation of thioacetals, gem-dihalides, and related organosulfur and organnhalogen compounds with the titanocene(II) reagent Cp2Ti[P(OEt)(3)](2). Alkylidene, heteroatom-substituted methylidene, 2-alkenylidene-, 2-alkynylidene-, and vinylidene-titanocenes thus formed are highly reactive toward organic compounds bearing a multiple bond and are employed for a variety of organic transformations such as carbonyl olefination and olefin metathesis.
