polyfluoroaryl imines with Grignard reagents were discovered in the absence of metal catalysts. The aldazine-N atom as an anchoring group has a special effect on the regioselectivity of the reaction. The C═N bond addition reaction with Grignard reagents was also explored. A possible mechanism was proposed on the competition between the nucleophilic substitution and addition reaction.
在没有金属催化剂的情况下,发现了用格氏试剂对多氟芳基亚胺的CF键进行选择性烷基化和芳基化。作为锚定基团的恶嗪-N原子对反应的区域选择性具有特殊的影响。还研究了与格氏试剂的C═N键加成反应。提出了亲核取代与加成反应竞争的可能机制。
