Abstract

Electrocatalytic biomass valorization has attracted increasing interest over the years. Amongst many possible products from biomass upgrading, pyridine-containing chems. are rarely reported. Herein, we describe an electrochem. synthesis of 3-pyridniol from biomass-derived furfurylamine in 0.1 M H2SO4, taking advantage of the Br-/Br+ redox cycle and the strong acidic condition in driving the final dehydration step. Such an electrosynthesis approach was able to achieve a 97% yield of 3-pyridinol from the nearly complete conversion of furfurylamine. A number of control experiments aided by computational investigation were carried out to elucidate the key mechanistic steps of the ''one-pot'' conversion of furfurylamine to 3-pyridinol.
