2,3-Dimethyl-2,3-diphenylbutane

2,3-Dimethyl-2,3-diphenylbutane is a minor product formed during the thermal decomposition of dicumyl peroxide (DCP) in cumene, generated through radical coupling reactions. As an initiator capable of producing free radicals, 2,3-dimethyl-2,3-diphenylbutane promotes cross-linking or decomposition processes via initiating free radical reactions in fields such as polymer polymerization (e.g., modification of polyphenylene oxide processing), organic synthesis (e.g., DCP decomposition reactions), and coal processing (e.g., oxidation stabilization of coal tar pitch), thereby enhancing material properties or reaction efficiency[1][2][3].
