WebPeroxy acids generate by thermal decomposition chiefly CO 2 and an alcohol, following the reaction indicated below: (6.4.1) Peroxy esters are common polymerization initiators [3]. These compounds decompose with the formation of two free radicals, and the main reaction is the formation of an ether, as shown below: WebIf the P state is indeed a peroxy intermediate (as indicated by PMand PR), internal electron transfer would regenerate the the oxidized centers. However, the spectroscopy suggests that the heme a3Fe is present in the Fe+IVstate, suggesting a possible ferryl state, as indicated by the boxed path.
