Direct nucleophilic fluorination of carbonyl groups of benzophenones and benzils with Deoxofluor
摘要:
The carbonyl groups of diaryl ketones and diaryl diketones were directly fluorinated with bis(2-methoxyethyl)aminosulfur trifluoride (Deoxofluor) under neat conditions to give the Corresponding gem-difluorides and tetrafluorinated derivatives in moderate to high yields.

Abstract The Ag(I)-catalyzed decarboxylative homocoupling from the difluoroacetate has been developed to the synthesis of symmetric CF2–CF2 containing dimers. This radical dimerization overpasses the prefunctionalization of the substrate and provides a direct and efficient method for construction of tetrafluoroethylene bridge-linked homodimers.
