Abstract The inductive constant σ* of the succinimide group was determined using the previously obtained equation correlating the rate constant kl ofliquid-phase homolysis of the O-NO 2 bond in nitro esters with the σ* constants of electronegative substituents. The kinetics of thermolysis of N-nitroxymethyl-and N-(2-nitroxyethyl) succinimide in the melt and solutions was studied manometrically. Adequate data for kl were obtained. The σ* ...
