Invited for this month's cover picture is the group of synthetic and physical chemists from the Czech Academy of Sciences. The cover picture shows electrochemical dechlorination of polychlorinated derivatives of bicyclo[1.1.1]pentane‐1,3‐dicarboxylic acid. Read the full text of the Article at 10.1002/celc.202100372.
“Reduction of five derivatives of bicyclo[1.1.1]pentane‐1,3‐dicarboxylic acid containing from one to four chlorine substituents on methylene bridges were investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Electrochemical cleavage of C–Cl bonds and the reduction of H+ provided by dissociation of COOH groups are two competing processes characterized by different time constants. Carboxylic groups participate in the protonation of intermediates formed by the C–Cl bond rupture. The esterification of two derivatives eliminates the self‐protonation…“ Learn more about the story behind the research featured on the front cover in this issue's Cover Profile.
