been studied. The reaction proceeds, depending on temperature, solvent or structure, either to expected 2-fluoro amines and 4-fluoro allylic amines or to elimination products. A type of Wagner-Meerwein rearrangement was observed and benzene as solvent gave a type of Friedel-Crafts reaction. The steric constraints may explain the differences in the yields of cis and trans addition products. Also, the
已经研究了三种同构的α,β-亚乙基氮丙啶通过HF-吡啶的开环。根据温度,溶剂或结构,反应进行到预期的2-氟胺和4-氟烯丙基胺或消除产物。观察到一种Wagner-Meerwein重排,并且苯作为溶剂产生了一种Friedel-Crafts反应。空间限制可以解释顺式和反式加成产物的产量差异。而且,刚性结构允许检测邻近的连接以及研究构造和构型。
