Nitrile Imines: Thermal Generation, Direct Observation, and Subsequent Trapping

Abstract

The first thermally generated nitrile imine, the species 2 (g) with non-isomerizing N-substituents, was generated from the tetrazole 1 by vacuum flash pyrolysis and characterized by mass spectrometry and IR spectroscopy. Both gaseous 2 (g) and 2 (s) isolated in a matrix can be trapped by cycloadditions.
