Gas-phase pyrolytic reactions. Rate data for the pyrolysis of phenyl-N-tert-butylcarbamate and the Hammett correlation for pyrolysis of N-tert-butylbenzamides

摘要

Rates of gas-phase thermal elimination of phenyl-N-tert-butylcarbamate have been measured between 593 and 648 K and compared to that of N-tert-butylbenzamide and N-tert-butylacetamide. Also the gas-phase elimination reaction of substituted N-tert-butylbenzamides into alkene and substituted benzamides have been studied. The data give a good correlation with σ~0 [value with ρ + 0.43 at 720 K.
