Regioselectiveopening of the thiiranering occurs spontaneously with Group IV B organometallics such as Me3SnNR2 and under the catalytic action of AlCl3 with Me3SiCN, affording difunctional thiols.
硫杂环戊烷环的区域选择性打开是与IV B B类有机金属(例如Me 3 SnNR 2)自发发生的,并且在AlCl 3与Me 3 SiCN的催化作用下产生双官能硫醇。

Downfield chemical shifts at ?-protons and carbons of ?-propiothiolactones
作者:Hee Bong Lee、Hyung-Yeon Park、Bon-Su Lee、Young Gyu Kim
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.
