Electrochemical Borylation of Carboxylic Acids [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
A simple electrochemically mediated method for the conversion of alkyl carboxylic acids to their borylated congeners is presented. This protocol features an undivided cell setup with inexpensive carbon-based electrodes and exhibits a broad substrate scope and scalability in both flow and batch reactors. The use of this method in challenging contexts is
