Reactions of Tetramesityldisilene with Azides: Synthesis of Disilaaziridines
Abstract
The reactions of several organic azides (RN3) with tetramesityldisilene (1) were studied. Azides with R=Ph or Mes each gave two products, a disilaaziridine and a disilatriazoline. When R=PhCH2 or Me3SiCH2 intermediate adducts of the azide and the disilene were found. These adducts and the disilatriazolines both react thermally to yield the respective disilaaziridines. For R=Me3Si only a disilaaziridine was observed, the structure of which was determined by x-ray crystallography and was found to have a short Si-Si internuclear distance of 2.23A. Crystal data: R = trimethylsilyl, a 23. 561(3), b 19.001(3), c 16.916(3)A, monoclinic, = 106.0950, C2/c, Z 8. Novel five-membered silicon heterocycles were isolated from the reactions of 1 with toluenesulfonyl azide and diphenylphosphonyl azide.
