- Alcohol-containing potassium organotrifluoroborates as starting reagents were prepared from their
corresponding dibromobenzenes through a sequential one-pot reaction. The oxidation reactions of these
substrates, which were carried out using 3.0 equiv of 8 N Jones reagent in acetone at 0 ℃, provided a high
yield of the desired carbonyl-functionalized compounds. In addition, the cross-coupling reactions of
these organocarbonyltrifluoroborates were successfully performed in the presence of 3 mol % of Pd
(PPh3)4 catalyst at 100 ℃.
