Generation and trapping of a 1,2,3-triazolium 1-unsubstituted methanide. A carbon analogue of the azole N-oxide: routes to pyrrolo[1,2-c][1,2,3]triazoles and substituted 1-aminopyrroles
Abstract
Trapping of the first azole N-unsubstituted methanide species, a carbon analogue of the ubiquitous azole N-oxide system is described; new synthetic routes to pyrrolo[1,2-c][1,2,3]triazoles and 1-aminopyrroles have resulted.
