Base-Catalyzed H/D Exchange Reaction of Difluoromethylarenes. | LitMetric

The budding deuteriodifluoromethyl group (CFD) is a potentially significant functional group in medicinal chemistry. Herein, we investigated -BuOK-catalyzed H/D exchange reaction of difluoromethylarenes in DMSO- solution. The method provides excellent deuterium incorporation at the difluoromethyl group. Meanwhile, the effect of a trace amount of DO in DMSO- solution on the deuteration reaction was also investigated.
