Carbene or not carbene? By utilizing [Cp 2 Ti(η 2 ‐Me 3 SiC 2 SiMe 3 )] (Cp=C 5 H 5 ) as both a reducing and a quenching agent in the reaction with RNCNR, the first paramagnetic dinuclear titanocene(III) carbene‐like complex is prepared in good yield. The complex features the topology of a four‐membered N‐heterocyclic carbene species but with a Ti III center as part of the heterocycle.
