Abstract
Heating 4-R-methoxy-1,3,5-triazin-2-ylnitroformaldoximes with nitriles leads not to the formation of 1,2,4-oxadiazoles but rather to dimerization of the intermediate 1,3,5-triazinylnitrile oxides to give furoxanes. The reaction of 4-R-6-methoxy-1,3,5-triazin-2-ylnitroformaldoximes with ammonia and amines gives 1,3,5-triazinylamidoximes, which upon acylation and subsequent intramolecular cyclization yield (5-R-1,2,4-oxadiazol-3-yl)-1,3,5-triazines.
