摘要

Epoxide formation by sulphur y1id insertion into aldehydes under heterogeneous conditions in the presence of small quantities of water is described. Trimethylsulphonium and S- methylthiolanium bromide and iodide have been studied. For all alkyl substituents the bromide gives better results than the iodide, this is interpreted in terms of the reaction mechanism. Under optimum conditions high yields of epoxides are obtained.
