AlCl3‑Mediated CHF2 Transfer and Cyclocondensation of Difluoromethoxy Functionalized o‑Phenylenediamines to Access N‑Substituted Benzimidazoles

Herein, we report for the first time a transition-metal-free frustrated Lewis pair (FLP) catalyzed CHF2 group migration from an oxygen atom to the neighboring nitrogen atom, which led to the synthesis of N-substituted benzimidazoles at room temperature with excellent yields, broad functional group t...
