摘要

Adamantanethione S-methylide (5) is an easily accessible thiocarbonyl S-ylide. Generated by N2 elimination from the cycloadduct of adamantanethione and diazomethane, the nucleophilic 1, 3-dipole 5 reacts in situ with thiocarbonyl compounds furnishing 1, 3- dithiolanes. 5 and carbon disulfide afford 1: 1 and 2: 1 cycloadducts. The structures are assessed by NMR spectra, a X-ray analysis, and CS hydrogenolyses. The C S group is ...
