1,3-Dipolar cycloadditions of diphenylnitrilimines with 2EtO-and 2EtS-tetramethyl-1-azetines (1a, b) are accompanied by ring-opening and loss of EtXH (X = O or S) to give 1,2,4-triazoles (3), whereas with N-(4-nitrophenyl) nitrilimines the expected cycloadducts and/or ring-opened products are formed.
1,3-Dipolar Cycloadditions of 2-Ethoxy- and 2-(Ethylthio)-1-azetines with Nitrile Oxides, Nitrile Ylides and Nitrilimines: An Unexpected 1,2,4-Triazole Formation.

2-Ethoxy- and 2-(ethylthio)-1-azetines readily undergo 1,3-dipolar cycloadditions with nitrile oxides and nitrile ylides to give stable 4,5-bicyclic cycloadducts.With nitrilimines, however, the expected 1,3-dipolar cycloadducts and/or unexpected ring-open
