Agostic interaction olefin metathesis

The saturated carbon C7 is only 2.293(7) A from Ti (and C2 is 2.579(7) A away). Remarkably C7 is closer to Ti than any of the bound olefinic carbons C4 and C5 (2.30-2.34 A) and Cp carbons, clearly indicative of metal C-C bond interaction. Similar interactions have been found in electron-deficient metallocyclobutane complexes, Cp 2M(CH2)2CHR (M = Ti and Zr but not 18e Mo and W analogues), which may have important implications in olefin polymerizations and metathesis. There is precedence for such interactions in an agostic C-Si interaction with Ti, and other C-X interactions are known. [Pg.693]
