ResumoThe reaction of the abbreviated as Si(NN)) with the imine Ph2CNSiMe3 gave a 1:1 adduct, the fused bicyclic compound Upon heating, 6 was transformed into the In contrast, treatment of 5 with PhCHNBut gave a 2:1 adduct, the Treatment of 6 with an equivalent of 5 yielded a related Plausible reaction pathways for these reactions are suggested. From 5 and the 1-aza- or 1,4-diazabutadiene PhCHCHCHNPh or ButNCHCHNBut, there was obtained the 1-aza-2-sila-4-cyclopentene 15 or the 1,3-diaza-2-sila-4-cyclopentene 16, respectively, by a formal [4 + 1] cycloaddition. Compounds 6−9, 15, and 16 have been characterized by multinuclear NMR spectroscopy and mass spectrometry (except for 15), and the structure of 8 was also determined by a single-crystal X-ray diffraction study.
