Abstract
The cycloaddition of 4-amino-3-azido-1,2,5-oxadiazole to nitriles with activated methylene groups has been studied, and 3-amino-4-(5-amino-1H-1,2,3-triazol-1-yl)-1,2,5-oxadiazoles and the products of their Dimroth rearrangement, viz, N-(4-R-1H-1,2,3-triazol-5-yl)-1,2,5-oxadiazole-3,4-diamines, have been synthesised.
