The reaction of anions from 1,2-bisimines with acid chlorides gives unacylated 2H-imidazoles. The unprecedented reactivity of these anions is interpreted by cyclization of the radical generated by electron transfer from the anion to the acid chloride.
来自1,2-二亚胺的阴离子与酰氯的反应得到未酰化的2 H-咪唑。这些阴离子空前的反应性是由电子从阴离子转移到酰氯所产生的自由基的环化所解释的。
