Study of a Stable “Trifluoromethoxide Anion Solution” Arising from 2,4‐Dinitro‐Trifluoromethoxybenzene

Résumé

Despite recent advances, trifluoromethoxylation remains a challenging reaction. Here we describe an efficient trifluoromethoxylative substitution, using an inexpensive and easy-to-handle reagent. By mixing DMAP with a slight excess of 1,4-dinitro-trifluoromethoxybenzene (DNTFB), a stable solution of trifluoromethoxide anion is obtained and can be used to perform a SN2 reaction without any silver additives. A precise study of the properties and behavior of this unusual stable solution of CF3O− species is also performed.
