mono and dimethyl derivatives. For comparison carbon-13 and oxygen-17 chemicalshifts of the corresponding S-dioxides are also reported. According to force field calculations and NMR data the conformation of S-oxides depends on the number and on the position of ring substituents. Oxygen-17 chemicalshifts of thiolane S-oxides are apparently not very sensitive to ring substitution and to the configuration
报告了硫烷S-氧化物及其几种单和二甲基衍生物的力场计算和1 H,13 C和17 O NMR数据。为了进行比较,还报道了相应的S-二氧化物的碳13和氧17的化学位移。根据力场计算和NMR数据,S-氧化物的构象取决于环取代基的数目和位置。硫烷S-氧化物的氧17化学位移显然对环取代和亚磺酰基的构型不是很敏感。但是,这是构象变化的结果,无法轻易预测。对于2-甲基衍生物δ 17 0允许容易识别的顺式和反式异构体的。

Reductive cyclisation of the 2-sulfonyl-5-hexenyl radical with tributyltin hydride in benzene at 80°C affords a 73:23 mixture of the sulfones derived from 5-exo- and 6-endo- ringclosure with a small quantity (4%) of reduced material; under identical conditions, the 2-thia-5-hexenyl radical gives a 70:13:17 mixture of the corresponding sulfides.
