T. Wohrle et U. Thewalt, TI COMPOUNDS WITH FULVALENE BRIDGES - THE STRUCTURE OF [CPTIME2]2(C10H8), Journal of organometallic chemistry, 456(2), 1993, pp. 30000021-30000023
X-ray analysis for the orange-yellow thermally unstable crystalline co
mpound [CpTiMe2]2(C10H8) (3(Me)), which results from methylation of [C
pTiCl2]2(C10H8), confirms the presence of a fulvalene bridge. The two
CpTiMe2 fragments in 3(Me) are trans with respect to the fulvalene gro
up.
