Fluoromethylation

WebOct 4, 2024 · The first direct and straightforward nucleophilic fluoromethylation of organic compounds is reported. The tactic employs a "fleeting" lithium fluorocarbenoid (LiCH 2 F) generated from commercially available fluoroiodomethane. Precise reaction conditions were developed for the generation and synthetic exploitation of such a labile species. WebJan 20, 2024 · Check out Abstract Ruthenium (II)-catalyzed meta -selective C−H (di)fluoromethylation was accomplished by phosphine and carboxylate cooperation. The remote C−H functionalization was characterized by ample substrate scope, thereby setting the stage for meta - (di)fluoromethylation through facile C−H cleavage. Supporting …
