Reactions of the hydrazinediido complexes [M(N2TBSNpy)(NNPh2)(py)] (M = Zr (1a), Hf (1b)) with (hetero)allenes result in a variety of [2 + 2] cycloaddition products of the general type [M(N2TBSNpy)(κ2N,E-(E(═E′R)NNPh2)(py)] (E = CH2, S; E′ = CH, N; R = alkyl, aryl). The reaction of [Zr(N2TBSNpy)(NNPh2)(py)] (1a) with 1 molar equiv of phenyl or mesityl isothiocyanate at room temperature yields [Zr(N2TBSNpy)(κ2N
