Abstract

Abstract The rates of gas-phase elimination of N-ethyl (1), N-isopropyl (2), Nt-butyl (3) substituted 2-aminopyrazine and N-ethyl (4), N-isopropyl (5), and Nt-butyl (6) substituted 2- aminopyrimidine have been measured. The compounds undergo unimolecular first-order pyrolytic reactions. The relative rates of the primary: secondary; tertiary alkyl homologues at 600 K are 1: 14.4: 38.0 for the pyrazines and 1: 20.8: 162.5 for the pyrimidines, ...
