Trifluoromethoxylation Reactions of (Hetero) arenes, Olefinic Systems and Aliphatic Saturated Substrates

Direct fluoroalkoxylation reactions of (hetero)arenes, carbon‐carbon multiple bonds, and substitution reactions at Csp3 carbon centers by CF3O, CHF2O, and (CF3)2CFO groups are discussed. Emphasis on thermal radical, electron transfer, photocatalytic, electrochemical and redox‐neutral radical methods are placed to accomplish fluoroalkoxylation reactions. All these methods employ either radical fluoroalkoxylating reagents or some nucleophilic trifluoromethoxylating sources of CF3O. A summary of all these methods is provided in Table 2.
