Ring-Opening of Donor-Acceptor Cyclopropanes by Boronic Acids and Potassium Organotrifluoroborates under Transition-Metal-Free Conditions.
The ring-opening of cyclopropane-1,1-dicarboxylates with vicinal donor aryl groups by boronic acids and potassium organotrifluoroborates under metal-free conditions has been developed. The reaction utilizes trifluoroacetic acid or boron trifluoride as promoters.
