Gas-phase pyrolysis of 2,3-dihydro-1,4-diazepines: involvement of the saturated portion of the ring in chemical reactions and novel cis–trans isomerisation of a fused ring system

Michael J. Ellis,   Douglas Lloyd,   Hamish McNab  and  Marion J. Walker  

Abstract

Flash vacuum pyrolysis of 2,3-dihydro-1,4-diazepines in the range 450–550 °C involves interaction of the saturated portion of the molecule with the vinamidine system and causes 1,5-hydrogen shifts which have been established by deuterium labelling experiments; at higher temperatures, ring contraction occurs to give pyrazines as major products.
