3-Ethyl-2-tetrazo-6-X-benzo[d]thiazolines and Their Reactivity: A Contribution to the Chemistry of Nucleophilic CarbenesThe 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 disscussed. 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 and tetracyanoethylene could be studied. Direct dimerisation of 1 to 2 (without acid/base catalysis) could not be found, as demonstrated by the behavior of 1e.
