The invention relates to a method for directly oxidizing arylboronic acid into heptafluoroisopropyl by utilizing hexafluoropropylene. The method comprises the following steps that silver fluoride is used as a fluorine source, under the effect of copper salt, the hexafluoropropylene and the arylboronic acid can be converted into a series of compounds containing heptafluoroisopropyl in organic solvents at the room temperature, and the reaction is also applicable to alkenylboronic acids. The method has the advantage that a series of compounds containing the heptafluoroisopropyl are synthesized through one-step reaction at high selectivity.

The copper-mediated aerobic reactions between the branched (CF3)2CFI and boronic acids (R-B(OH)2) are described. Different from the linear perfluoroalkyl analogs CF3(CF2)nI (n?=?2, 3, 5, 7), (CF3)2CFI reacting with R-B(OH)2at room temperature under air in the presence of catalytic Cu powder provided exclusively the corresponding iodides (R-I), while the aerobic reactions of arylboronic acids with (CF3)2CFI at room temperature in the presence of Cu(OAc)2gave the perfluoroalkylation products (R-CF(CF3)2) in acceptable to moderate yields. The iodination reaction could be further promoted by hydroquinone, the addition of which improved the oxidation ability of (CF3)2CFI and provided the ipso-iodination products in high yields. The perfluoroalkylation was facilitated by the copper carboxylates since the addition of these salts into the reaction mixtures could successfully give rise to Ar-CF(CF3)2.

A novel and straightforward strategy for heptafluoroisopropylation of arylboronic acids at room temperature has been developed. This method, directly using commercial available hexafluoropropene (HFP) as the starting material, provides a new way to synthesize a variety of synthetically useful heptafluoroisopropylated arenes.
