  The synthesis of difluoromethyl ethers and sulfides with a simple, non-ozone- depleting reagent is described. The difluoromethylation of phenols with this reagent occurs at room temperature within minutes with exceptional functional group tolerance. The mild conditions makes possible tandem processes for the conversion of aryl boronic acids, aryl halides and arenes to difluoromethyl ethers. Mechanistic studies support a reaction pathway involving nucleophilic attack of the phenolate to difluorocarbene.

  描述了使用一种简单、无臭氧破坏剂的方法合成二氟甲基醚和硫醚。使用这种试剂对酚进行二氟甲基化反应在室温下几分钟内就能完成，并且具有异常的官能团容忍性。温和的条件使得可能进行串联过程，将芳基硼酸、芳基卤代烃和芳烃转化为二氟甲基醚。机理研究支持一个涉及酚酚根攻击二氟卡宾的反应途径。

• Use of Fluoroform as a Source of Difluorocarbene in the Synthesis of Difluoromethoxy- and Difluorothiomethoxyarenes

  Fluoroform, CHF3, a non-ozone-depleting, nontoxic, and inexpensive gas can be used as a difluorocarbene source in a process for the conversion of phenols and thiophenols to their difluoromethoxy and difluorothiomethoxy derivatives. The reactions are carried out at moderate temperatures and atmospheric pressure, using potassium hydroxide as base in a two-phase (water/dioxane or water/acetonitrile) process to provide moderate to good yields of the respective products.
