摘要：
2,2-Dimethyl-3-[(4-methylphenyl)sulfonyl]-2,3-dihydro-1,3,2-benzoxazasilole was synthesized by the reaction of N-(2-hydroxyphenyl)-4-methylbenzenesulfonamide with dimethyldichlorosilane or N,N-bis(dimethylamino)dimethylsilane in 68 and 96% yield, respectively. The structure of the new compound was assigned using NMR and IR spectroscopy and confirmed by X-ray diffraction. In the crystal, the silole molecules are linked to each other by short O center dot center dot center dot H-C contacts (similar to 2.6 angstrom) between the oxygen atoms of the bicyclic moiety and the methyl hydrogen atoms of adjacent molecules.
