Electrochemical cells for the reductive amination of furfural-based molecules are provided. Also provided are methods of using the electrochemical cells to carry out the electrochemical reductive amination reactions. Using the cells and methods, furfural-based molecules can be converted into amines via the conversion of their formyl groups to amine groups.

A process for preparing furanic mono- and/or di-sulfonate molecules from the reduction products of HMF, in particular, from either 2,5-bis-hydroxymethyltetrahydrofurans (THF-diols) or furan-2,5-dimethanol (FDM) under relatively mild conditions is described. The process involves reacting THF-diols or FDM with at least a sulfonate species, and a reagent of either 1) a nucleophilic base or 2) combination of a non-nucleophilic base and a nucleophile, as two separate reagents. The furanic sulfonates synthesized according to the process and some of the associated compounds that can be derivatized from the sulfonates are also provided.

reaction conditions. The conversion of HMF to BMIF underwent the fast amination of HMF to 5-(methyl-iminomethyl)furfuryl alcohol (MIFA), the subsequent rate-limiting oxidation of MIFA to 5-(methyl-iminomethyl)furfural (MIFF) and the final fast amination of MIFF to BMIF. The quick amination of MIFF to BMIF drove the oxidation reaction equilibrium toward MIFF from MIFA, which ensured the highly efficient conversion
