Liu, Xi-Hai published the artcileCopper-mediated aerobic iodination and perfluoroalkylation of boronic acids with (CF3)2CFI at room temperature, Synthetic Route of 69626-75-1, the publication is Journal of Fluorine Chemistry (2016), 59-67, database is CAplus.
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)2 at 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)2 gave 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.
