A carbene strategy for the sequential (deutero)hydrodefluorination of fluoroalkyl ketones is reported. This method allowed for the controllable preparation of difluoroalkyl- and monofluoroalkyl ketones from aryl- and alkyl-substituted perfluoroalkyl ketones in high yield with excellent functional group tolerance.

The use of TFEDMA, a fluoroalkyl amino reagent, for the difluoromethylation and difluoroacylation of arenes, heteroarenes, and C-H acidic compounds is reported. This approach allows for an efficient access to difluoromethylated products of high added value in good to excellent yields and with scale-up possibilities.
