Two silylene molecules oxidatively react under formal [1 + 2 + 1]-cycloaddition to the C≡N bond of nitriles to yield 1-aza-2,4-disilabicyclo[1.1.0]butanes (L)(Cl)Si[μ-η 1,2 -NC( p -RC 6 H 4 )]Si(Cl)(L) (L = PhC(N t Bu) 2 , R = CF 3 ( 2 ), F ( 3 ), Cl ( 4 ), Br ( 5 )). The strongly folded bicyclic SiCNSi cores in 2 - 5 feature inverted bridgehead carbon atoms and superelongated C-N bonds [1.745(12) to 1.801(2) Å], exceeding the lengths of C-N single bonds in known silaaziridines by up to 23%. Detailed bonding analysis discloses C-N bonding interactions, sharing far-reaching similarities with the central C-C bond in [1.1.1]propellane. |
