N‐(1,3‐Thiazol‐5(4H)‐yliden)amine aus 1,3‐dipolaren Cycloadditionen von Aziden mit 1,3‐Thiazol‐5(4H)‐thionen

Abstract: (Table). A reaction mechanism for the formation of these scarcely investigated thiazole derivatives is formulated in Scheme 3:1,3-Dipolar azide cycloaddition onto the C=S group of 2 leads to the 1 : 1 adduct C. Successive elimination of N, and S yields 6, probably uiu an intermediate thiaziridine E.

“…[8] Similarly, thiaziridines have been postulated as intermediates in transformations of thiocarbonyl S-imides into imines. [9][10][11] In our recent studies on reactions of thiocarbonyl compounds with organic azides, thiaziridines were proposed as key intermediates in the sulfur-transfer process leading to the in situ formation of thiocarbonyl S-sulfides, which further react to give 1,2,4-trithiolanes. [12] As a possible precursor of a thiaziridine, the stable thiocarbonyl S-imide 1 was thermolyzed under FVP-conditions.…”
