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