REACTIONS OF AZINES WITH TITANOCENE : C-H ACTIVATION, C-C COUPLING, AND N-N CLEAVAGE TO HETEROBIMETALLIC COMPLEXES

Either C−H activation or C−C coupling is observed in reactions of titanocene with azines (R1R2CN−NCR1R2), which lead to the formation of complexes 2 and 3, respectively. The reaction with two different metallocene units can yield heterobimetallic bis(alkylideneamido) complexes (4).
