A break from the norm: Contrary to traditional understanding, the present work suggests that PEDOT:PSS/H2SO4 supercapacitors operate by an electrostatic (or nonfaradaic) charge storage/delivery mechanism. The operatio...

Electrochemical Incorporation of Electrophiles into the Biomass‐Derived Platform Molecule 5‐(Chloromethyl)furfural
Von Wiley-VCH zur Verfügung gestellt
Reagent-free electrosynthesis is an emergent methodology in sustainable chemistry and is applied here to a derivative of 5-(chloromethyl)furfural (CMF), one of the most versatile biobased platform molecules. Incorporating the greenhouse gas CO2 into this platform gives a diacid derivative that is formally a furylogous malonate. Moreover, cathodic dehalogenation of CMF is also seen as superior to the use of chemical reducing agents.
Abstract
The 5-(chloromethyl)furfural (CMF) derivative ethyl 5-(chloromethyl)furan-2-carboxylate undergoes two-electron electrochemical reduction in a simple, undivided cell to give the corresponding furylogous enolate anion, which can either be quenched with carbon dioxide to give a 5-(carboxymethyl)furan-2-carboxylate or with hydrogen ion to give a 5-methylfuran-2-carboxylate, thereby expanding the derivative scope of CMF as a biobased platform molecule.
