oxidative difluorination of alkenes represents an important strategy for their preparation, yet current methods are limited in their alkene-types and tolerance of electron-rich, readily oxidized functionalities, as well as in their safety and scalability. Herein, we report a method for the difluorination of a number of unactivated alkene-types that is tolerant of electron-rich functionality, giving products

Fluorination of styrene derivatives with a reagent system composed of mu-oxo-bis[trifluoroacetato(phenyl)iodine] and a pyridine.HF complex gave the corresponding (2,2-difluoroethyl)arenes in good yields. Similarly, the reagent of PhI(OCOCF3)(2) and the pyridine.HF complex acted as a fluorinating agent for styrene derivatives. The fluorination of styrene derivatives with the pyridine. HF complex underwent under catalytic conditions using 4-iodotoluene as a catalyst and m-CPBA as a terminal oxidant.
