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 Csp 3 carbon centers by CF 3 O, CHF 2 O, and (CF 3 ) 2 CFO 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 CF 3 O. A summary of all these methods is provided in Table 2.
