Abstract

The class of compounds known as sulfines (thione 5-oxides) has been known for many years and numerous compounds with this structural feature have been prepared, especially in the last few years2, 3. In addition to the more familiar routes from sulfinyl chlorides by/3- elimination and from thiones by oxidation, sulfines can now also be prepared in several cases from active methylene compounds via reaction of the corresponding silylated ...
