Abstract
Flash vacuum pyrolysis of 2,3-dihydro-1,4-diazepines in the range 450- 550 degrees C involves interaction of the saturated : portion of the m olecule with the vinamidine system and causes 1,5-hydrogen shifts whic h have been established by deuterium labelling experiments; at higher temperatures, ring contraction occurs to give pyrazines as major produ cts.
