In contrast to 2-methylbenzoyloxyl radicals, 2,6-dimethylbenzoyloxyl and 2,4,6-trimethylbenzoyloxyl radicals decarboxylate efficiently rather than transfer a hydrogen atom, as observed by transient absorption spectroscopy and product distribution.
与2-甲基苯甲酰氧基基团相反,如通过瞬态吸收光谱法和产物分布所观察到的,2,6-二甲基苯甲酰氧基基团和2,4,6-三甲基苯甲酰氧基基团有效地脱羧而不是转移氢原子。
