The isolation of radical coupling products and the observation of appropriate C.I.N.D.P. signals suggest that most of the title reactions proceed by homolysis of the anhydro-bases (4) or (9) followed by radical recombinations; a diaza-oxy-Cope rearrangement may still account for the formation of α-acylamination products.
自由基偶联产物的分离和对适当CI
NDP信号的观察表明,大多数标题反应是通过脱
水碱(4)或(9)均质化,然后进行自由基
重组而进行的。重氮-氧基-Cope重排仍可能解释了α-酰化产物的形成。
