The crystalline compounds NSi(NN)Si(NN)CR [R = Bu t ( 2 a ), Ad ( 2 b )], (NN)Si(Bu t )CN ( 3 ), Bu t Si(NN)Si(NN)CN ( 4 ), AdNSi(NN)Si(NN) ( 5 ), AdNN=NN(Ad)Si(NN) ( 6 ), (NN)Si(N 3 )N(SiMe 3 ) 2 ( 7 ) and Me 3 SiNSi(NN)Si(NN)(thf) ( 8 ) were obtained in good yield under mild conditions from Si[(NCH 2 Bu t ) 2 C 6 H 4 ‐1,2] [≡ Si(NN)] and the appropriate reagent RCN, Bu t NC and R′N 3 . The compounds 2 – 8 were characterised by microanalysis, multinuclear NMR and (not 8 ) mass spectra, as well as for 2 a , 4 and 7 single crystal X‐ray diffraction data. The results are placed in context of data in the literature on reactions of especially Si[N(Bu t )CH=] 2 , (SiBu t 2 ) 3 , Mes 2 Si=SiMes 2 with (where available) a nitrile, isonitrile or azide. Reaction pathways are discussed.
