Abstract Various titanium carbene complexes are prepared by the reductive titanation of thioacetals, gem ‐dihalides, and related organosulfur and organohalogen compounds with the titanocene(II) reagent Cp 2 Ti[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. © 2007 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.
