The reactions of three-coordinate iron(0) and cobalt(0) alkene complexes (NHC)M(η²-CH₂CHSiMe₃)₂ (NHC = N-heterocyclic carbene, M = Fe, Co) with organic azides proved an effective way for the preparation of iron and cobalt terminal imido complexes. The relevant reactions of nickel(0) alkene complex (NHC)Ni(η²-CH₂CHSiMe₃)₂ with organic azides, however, have remained unexplored. Herein, we report the study on the reactions of [(IPr)Ni(η²-CH₂CHSiMe₃)₂] (IPr = 1,3-bis(2′,6′-diisopropylphenyl)imidazole-2-ylidene) with organic azides. The interaction of [(IPr)Ni(η²-CH₂CHSiMe₃)₂] with 2,6-dimesitylphenyl azide (DmpN₃) produced the two-coordinate imido complex [(IPr)Ni(NDmp)] (1) in a trace amount with the starting materials being largely remained. The reaction of [(IPr)Ni(η²-CH₂CHSiMe₃)₂] with 2,6-diisopropylphenyl azide (DippN₃) gave IPrNNNDipp (2) as the only isolable product. The interaction of [(IPr)Ni(η²-CH₂CHSiMe₃)₂] with Ph(F₃C)₂CN₃ produced an azanickelacyclobutane compound [(IPr)Ni(κ-C,N–N(C(CF₃)₂Ph)CH(SiMe₃)CH₂)] (3) in high yield. The different products formed in these reactions reflect the influence of the steric and electronic nature of organic azides on reaction outcomes. Further study on the azanickelacyclobutane complex 3 indicated that it can convert into a new azanickelacyclobutane [(IPr)Ni(κ-C,N–N(C(CF₃)₂Ph)CH₂CHSiMe₃)] (4). A nickel(II) amido alkyl complex [(IPr)Ni(NHC(CF₃)₂Ph)(CH₂CHNC(CF₃)₂Ph)] (5) was also isolated from the decomposition reaction of 3.
