  • Photofragmentation reactions of dithiolactones
    作者:Kayambu Muthuramu、Bhagavathi Sundari、Vaidhyanathan Ramamurthy

    日期:1983.1
    The occurrence of Norrish type-I α-cleavage has been established in β-dithiolactones, involving the n-π* singlet state (diradical and carbene reactive intermediates). Concerted ring expansion to a thiacarbene from the excited state is suggested to be responsible for the formation, at least in part, of one of the cyclic thioacetals. Although this α-cleavage process is similar to that of corresponding

  • (3+2)‐Cyclization reactions of unsaturated phosphonites with aldehydes and thioketones

    Unsaturated phosphonites are excellent substrates in new (3+2)-cyclization reactions with aldehydes or thioketones. The cyclisation reactions proceed smoothly at room temperature and lead to the fast formation of the previously inaccessible phosphorus heterocycles 1,3-oxa- and 1,3-thiaphosphole-3-oxides in good to excellent yields.
    在与醛或硫酮的新 (3+2)-环化反应中,不饱和亚膦酸酯是极好的底物。环化反应在室温下顺利进行,并导致以前无法获得的磷杂环 1,3-oxa- 和 1,3-thiaphosphole-3-oxides 的快速形成,收率良好。
