The scope of the title process has been studied, showing that anions 4â² having RÂ =Â H, (substituted) Ph and CO2Me react cleanly (and still satisfactorily in the case RÂ =Â Me), while with RÂ =Â COMe, COAr and CN extensive decomposition occurs. The experimental findings (rate constants, activation parameters) have been elucidated through PM3 calculations.

A literature finding with 4(5)-azido-v-triazolide is reinterpreted as showing the occurrence of the title reaction; this constitutes a new kind of v-triazole ring transformation.
