Synthesis, Characterization, and Applications of Zwitterions Containing a Carbanion Moiety1. Issue 5 (13th December 2012) - Yanai, Hikaru
Abstract A 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).
