The endo confrontation of monoacyl and 1,3-diacylbenzimidazoline-2-thiones is predominant at ambient temperatures. Nmr temperature-dependent studies suggest that this is also true over a wide range of temperatures. In agreement with previous results

3-Substituted 1,2,3-benzotriazin-4(3H)-one 1-oxides are formed on peracid oxidation of 3-alkyl- and 3-methoxy-1,2,3-benzotriazin-4(3H)-ones. The 3-(α-alkoxyalkyl) 1-oxide derivatives could be dealkylated to the tautomeric 3-unsubstituted compound. T
