Abstract

Reaction of Di(tert-butyl)- and Diphenyldiazomethane and 1,3-Thiazole-5(4H)-thiones: Isolation and Crystal Structure of the Primary Cycloadduct Reactions of diazo compounds with C=S bonds proceed via the formation of thiocarbonyl ylides, which, under the reaction conditions, undergo either 1,3-dipolar cycloadditions or electrocyclic ring closure to thiiranes (Scheme 1). With the sterically hindered di(tert-buty1)diazomethane (2c), 1,3-thiazole-5(4H)-thiones 1 react to give spirocyclic 2,S-dihydro-1,3,4-thiadiazoles 3 (Scheme 2 ). Thes
