โฆ Synopsis
Reactions of the sterically encumbered silylenes R 2 Si: (R = respectively. The reactions of these silylenes with 1adamantyl azide seem to proceed through the silanimines 2,4,6-Me 3 C 6 H 2 , 2,4,6-iPr 3 C 6 H 2 ) with azobenzene are thought to proceed via the [2+1] cycloaddition products, followed by and 4-azahomoadamantene intermediates which, by [2+2] cycloadditions, afford the 1,3-diaza-2-silacyclobutane insertion of the N-N single bond into the ortho-C-H bond of one of the phenyl rings or into the C-HMe 2 bond of one of derivatives 11 and 12. The structures of 4, 5, 11, and 12 were determined by X-ray crystallography. the ortho-isopropyl groups to furnish the 1,3-diaza-2silaindan (4) or 1-aza-2-silaindan (5) derivatives,
