trifle of triflyl: N‐substituted anilines react with 1,1,3,3‐tetrakis(triflyl)propane to give a 2,2‐bis(triflyl)ethyl group at the para position of the ring. The product is a zwitterion with a carbanion and an ammonium moiety, and can be used as an acid catalyst for organic reactions (see scheme).
triflyl:N-取代的苯胺的一个琐事与1,1,3,3-tetrakis(triflyl)丙烷反应 ,在环的对位产生2,2-bis(triflyl)乙基。该产物是具有碳负离子和铵部分的两性离子,可以用作有机反应的酸催化剂(参见方案)。
