摘要

Abstract: The Arrhenius equation for the ring-opening isomerization of cyclopropylmethyl radicals (R') to 3-buten-1-yl radicals (R'.) for the 303-362 K temperature range was determined by thermolysis of (cyclopropylmethyl)(1-hydroxy-1-methylethy1) diazene in the presence of excess 1, 1, 3, 3-tetramethylisoindolin-2-yloxy (Y). Rate constants for coupling of R'with Y'were assumed to be proportional to diffusion-controlled rate constants (kd) and ...
