Abstract

Summary The synthesis of 3-ethyl-2-tetrazo-6-X-benzo [d] thiazolines 3-a new class of azohomologous diazo compounds-by addition of azide ions to azidinium salts 4 is described, their structure and some of their reactions are discussed. The thermolysis of 3 at ca. 270 K in DMFA or THF generates nucleophilic carbenes 1, whose trapping by electrophilic compounds such as 3, 4, diazonium salts, diazo compounds, methanol, sulfur ...
