STUDIES OF REACTIVE INTERMEDIATES USING MATRIX AND GAS-PHASE TECHNIQUES

In the direct investigation of reactive intermediates it is particular ly valuable to use a combination of several spectroscopic techniques. This commentary highlights recent examples, using primarily flash vacu um thermolysis for the generation of the intermediates, and matrix IR spectroscopy in conjunction with gas-phase mass spectrometric methods for their identification. The examples include nitrile imines, nitrile ylides, nitrile sulfides and selenides, dinitrogen sulfide and severa l novel cumulenes (X=C=C=Y, RN=C=C=C=X). (C) 1998 John Wiley & Sons, L td.
