    Regioselective opening of the thiirane ring occurs spontaneously with Group IV B organometallics such as Me3SnNR2 and under the catalytic action of AlCl3 with Me3SiCN, affording difunctional thiols.

  • Downfield chemical shifts at ?-protons and carbons of ?-propiothiolactones
    作者:Hee Bong Lee、Hyung-Yeon Park、Bon-Su Lee、Young Gyu Kim
    DOI:10.1002/1097-458x(200006)38:6<468::aid-mrc675>3.0.co;2-f
    日期:2000.6
    Both the alpha-protons and carbons of beta-propiothiolactones exhibit atypical downfield chemical shifts. The alpha-protons of beta-propiothioiactones with no heteroatom at the alpha-position appear at 3.53-5.35 ppm, whereas the alpha-carbons appear at 56.9-86.2 ppm. The major cause of the unexpected deshielding effect was rationalized by assuming a through-space interaction between the occupied orbital of the alpha-carbon and the vacant orbital of sulfur, Copyright (C) 2000 John Wiley & Sons, Ltd.
