摘要：

The reactions of the Group 4 metallocene alkyne complexes rac-(ebthi) M(eta(2)-Me3SiC2SiMe3) (1a: M = Ti, 1b: M = Zr; rac-(ebthi) = rac-1,2-ethylene-1,1'-bis(eta(5)-tetrahydroindenyl)) with Ph-C N were investigated. For 1a, an unusual nitrile-nitrile coupling to 1-titana-2,5-diazacyclopenta-2,4-diene (2) at ambient temperature was observed. At higher temperature, the C-C coupling of two nitriles resulted in the formation of a dinuclear complex with a four-membered diimine bridge (3). The reaction of 1b with Ph-C N afforded dinuclear compound 4 and 2,4,6-triphenyltriazine. Additionally, the reactivity of 1b towards other nitriles was investigated.
