CommunicationSelective O-difluoromethylation of 1,3-diones using S-(difluoromethyl) sulfonium salt

Add time:09/03/2019    Source:sciencedirect.com

A facile and highly efficient approach for selective O-difluoromethylation of 1,3-diones by recently developed bench-stable S-(difluoromethyl)sulfonium salt was described. And a broad range of difluoromthyl enol ethers were readily accessed in good to excellent yields under mild reaction conditions. Mechanistic studies revealed that the O-difluoromethylation reaction proceeds mainly via a difluorocarbene pathway.
