Abstract

By RIKUHEI TANIKAGA," YUJI HIRAKI, NOBORU ONO, and ARITSUNE KAJI (Department of Chemistry, Faculty of Science, Kyoto University, Sakyo-ku, Kyoto 606, Japan) ... Summary Sulphides (5) and thiols (6) react instantly with the Pummerer rearrangement intermediates (3) at 0 "C to give sulphonium salts (7) and dithioacetals (S), respec- tively. ... THE Pummerer rearrangement has been suggested to proceed via a sulphonium ion and a sulphur-stabilized carbonium ...
