说明

一般說明

2-Chloro-2,2-difluoroacetophenone is a difluorocarbene reagent, which is generally used in the synthesis of 2,2-difluoro enol silyl ethers, and gem -difluoromethene derived compounds.

應用

2-Chloro-2,2-difluoroacetophenone can be used:

• As a reagent in the difluoromethylation of various phenols to yield aryl difluoromethyl ethers.
• As a precursor in the Baylis-Hillman reaction of fluoroalkyl ketones to obtain chlorodifluoromethyl containing products.
• As a substrate in the synthesis of propargyl alcohols using a novel ruthenium catalyst.

Reagent is an effective product for the synthesis of difluoromethylated phenols in the presence of mild base and aqueous solvent.
