| Abstract: | Thermolysis of 5-amino-4-methyl-4-methoxycarbonyl-Δ2-l,2,3-triazolines leads to amidines and 1-methoxycarbonyl diazoethane. If the N1 substituent is a tosyl or benzoyl group, the corresponding triazoline is not isolated, the azide addition to the olefin gives directly the thermolysis products at room temperature. Triazoline photolysis leads to amino aziridines which are azomethine ylids. |
