Abstract

Thermolysis of 1, 2, 3-triazolines 4, 5, 6 leads to the corresponding aziridines only when X= Y= CO2Me, and then with a very low yield. However, photolysis or evolution in the presence of trifluoroacetic acid gives good results when carried out at sufficiently low temperature. The thermolysis study of 4-6 shows a new route to 1, 2, 3-triazoline decomposition that has not yet been mentioned in the literature. The easy elimination of the paratoluenesulfonate or ...
