A convenient, highly efficient, and selective transformation of aliphatic and aromatic carboxylic acids to acyl fluorides is reported. In contrast to established approaches that require toxic or volatile additives and base and reaction control (i.e., cooling, slow addition), this protocol allows for a straightforward access to various R-COF entities upon direct reaction with the bench-stable, solid
据报道,将脂肪族和芳香族羧酸方便,高效且选择性地转化为酰基氟。与需要有毒或挥发性添加剂以及碱和反应控制(即冷却,缓慢添加)的既定方法相比,该方案可以在与稳定的固体试剂直接反应后直接访问各种R-COF实体(在室温下为Me 4 N)SCF 3。该方法无碱和无添加剂,与后期合成应用程序兼容,具有较高的官能团耐受性,并且可通过过滤轻松纯化目标化合物。
