Abstract: The rate of decomposition of 4'-substituted-2-azidobenzophenones to give 4'- substituted-3-phenyl-anthranils has been studied in decalin over a 45'temperature range. The reaction was found to be accelerated by electron-withdrawing groups and retarded by electron-donating groups. The enthalpy of activation was found to be considerably less than reported for phenyl azide decompositions. The entropy of activation was moderately large ...
