Titanocene diphenylacetylene complex

The formation of highly substituted titanacyclobutenes utilizing titanocene-alkylidenes has been investigated (Scheme 14.33). Alkylidenetitanacyclobutenes 76 are produced by the reaction of titanocene-alkenylidene complexes with alkynes [76]. The alkenylcydopro-pane 77 can be synthesized by thermolysis of dicydopropyltitanocene in the presence of diphenylacetylene, which is assumed to proceed through formation of the titanacyclobutene 78 [25c],... [Pg.494]

Probably the first metallacyclopropene containing a Group IV metal that has been isolated and characterized is a diphenylacetylene-titanocene complex (40) prepared by the reaction of (OC)2TiCp2 with di-phenylacetylene, as in equation (37). Its structure was established primarily by X-ray crystallography. [Pg.1174]
