Argentination of Fluoroform: Preparation of a Stable AgCF 3 Solution with Diverse Reactivities.
ANGEWANDTE CHEMIE-INTERNATIONAL EDITION(2019)
摘要
The transformation of a large-volume industrial by-product and stable greenhouse gas fluoroform (HCF3) to useful products has recently received significant attention. Now, a simple and scalable preparation of AgCF3 by treatment of HCF3 with t-BuOK and AgOAc is disclosed. The reactivity of the HCF3-derived AgCF3 has been demonstrated by hydrotrifluoromethylation of alkenes and C-H trifluoromethylation of (hetero)arenes. This work not only provides a new avenue for the utilization of HCF3, but also presents a reliable and easy-to-execute synthesis of the relatively stable AgCF3 solution.
