and unsaturated acyl radicals, RĊO, have been generated in fluid solution, principally by the photolysis of di-t-butyl peroxide in the presence of the corresponding aldehyde. Most of the acyl radicals show well-resolved hyperfine splittings, and the values of a(Hβ) correlate with the n.m.r. coupling constants 3J(CHCHO) in the parent aldehyde. It is concluded that the acyl radicals and the corresponding
在流体溶液中已经产生了一系列饱和和不饱和的酰基R 1 O,主要是通过在相应的醛存在下对二叔丁基过氧化物进行光解。大部分的酰基的显示良好分辨的超精细分裂,和的值一(H β)关联与NMR耦合常数3 Ĵ(C ħ Ç ħ O)在父醛。结论是,酰基和相应的醛具有相似的结构。
