The TiQNNMe2 group of Cp*Ti{MeC(NiPr)2}(NNMe2) undergoes 1,2-addition with Si–Cl and reversible addition with Si–H bonds of RSiH2X (R=Ph or Bu; X=Cl or H). Labeling studies show that the so-formed silylhydrazide–hydride products react with primary silanes or H2 via r-bond metathesis between Ti–H and either Si–H or H–H. Terminal Group 6 transition metal hydrazides
