Various types of α-bromo aldehyde and ketone derivatives of nitroxyl radicals can be prepared in a selective bromination reaction with pyrrolidone hydrotribromide in the presence of a double bond. The saturated α-bromo aldehydes are dehydrobrominated with 1,8-diazabicyclo [5,4,0]undec-7-ene.
在双键存在的情况下,通过与吡咯烷酮氢溴酸盐进行选择性溴化反应,可以制备各种类型的δ-溴醛和酮衍生物。饱和δ±-溴醛与 1,8- 二氮杂双环 [5,4,0]undec-7-ene 发生脱氢溴化反应。
