A reaction for H–F bond insertion into α-diazo carbonylcompounds is reported. The protocol describes a simple reaction setup employing commercially available HF·pyr (Olah reagent) as the fluorine source. The method is rapid and practical, and allows access to a broad range of α-fluorinated carbonylcompounds in generally good yields.
We herein describe a new method for nucleophilic fluorine substitution of alkylbromides using Et3N·3HF. The process is characterized by a broad substrate scope, good functional-group compatibility, and mild conditions and provides a variety of alkylfluorides including tertiary alkylfluorides that are versatile and structurally attractive.
我们在此描述了一种使用 Et 3 N·3HF 亲核氟取代烷基溴的新方法。该工艺具有底物范围广、官能团相容性好、条件温和等特点,可提供多种烷基氟化物,包括叔烷基氟化物,用途广泛且结构有吸引力。
