instability of the generated carbanion that can evolve into a fluorocarbene. A method for the deprotonative functionalization of these compounds is described herein under an organocatalytic system using various electrophiles, and is also applied to a related α,α-difluoromethyl sulfoxide. This strategy gives access to highly valuable difluoromethylene scaffolds.
α,α-二
氟甲基酮的去质子化由于生成的碳负离子不稳定而可能演变成
氟卡宾,因此未得到充分研究。本文描述了使用各种亲电试剂在有机催化系统下对这些化合物进行去质子化功能化的方法,该方法也适用于相关的 α,α-二
氟甲基亚砜。该策略提供了获得非常有价值的二
氟亚甲基支架的途径。
