Recent advances in new trifluoromethoxylation reagents

The trifluoromethoxy (CF3O) group has become a novel moiety in various fields because of its unique features. However, despite the promising applications, the synthesis of CF3O-containing compounds is still a challenge due to indirect synthetical strategies and volatile reagent which is hard to handle. Until very recently, several innovative reagents were developed to facilitate the trifluoromethoxylation reaction and make CF3O-containing compounds more accessible. This review mainly focuses on the recent advances in new trifluoromethoxylation reagents and their usage.
