labelling experiments and diffusion control reactions, the formation of 5-H could be explained by a radical mechanism. The reduction of 4-pyr and 4-iPr using one-electron reducing agents also gave the rearranged products 13-pyr and 13-iPr in 21 and 19% yields, respectively, via C–N bond cleavage and B–N bond formation. The mechanism for the formation of 13-pyr and 13-iPr is suggested to contain a benzylic
路易斯碱稳定difluoroboranes 2,4-PYR和4-我镨,具有恶唑啉-或胺系酰胺配体被合成并充分表征。用KC 8处理2导致其完全消耗,重排的产物5-H(可能源自C-O键断裂和B-O键形成)可以作为18%收率的主要含浸产物分离出来。 。从氘标记实验和扩散控制反应,可以用自由基机理解释5-H的形成。的还原4-PYR和4-我镨使用单电子还原剂也给了重排产物13-PYR和13-我镨通过C–N键的裂解和B–N键的形成,分别获得21%和19%的产率。对于形成的机构13吡和13-我镨建议将含有苄型基团中间体。
