O-Difluorodeuteromethylation of phenols using difluorocarbene precursors and deuterium oxide†
Abstract
The first O-difluorodeuteromethylation of phenols using commercial diethyl bromodifluoromethylphosphonate and deuterium oxide to prepare various difluorodeuteromethyl aryl ethers is reported. This facile method affords a convenient way to introduce OCF2D groups into organic molecules.
