An apparatus for real‐time in‐situ monitoring of electrochemical advanced oxidation processes using visible spectrophotometry has been developed. Central to the design is a 3D‐printed sleeve that interfaces commercially available electrochemical and spectrophotometry units. Using the anodic oxidation of Acid Orange 7 as a test bed, the apparatus has been used for probing the impact of varying electrode composition, current density, electrolyte concentration, and stirring speed on the rate of decolorization. In addition, the unit was used to prove that decolorization can continue after electrolysis has been stopped, thereby showing the inherent value of real‐time monitoring. Given that a significant challenge in the field of advanced oxidation processes is the inability to compare different reported systems, our approach, using commercially available equipment and a printable interface may open avenues for more standardized data collection.

A methodology for the oxidative amidation of aldehydes to yield N‐acyl azoles is reported. The approach employs sodium persulfate and a catalytic amount of a nitroxide and is applicable to a range of structurally diverse substrates. [ABSTRACT FROM AUTHOR]

[Display omitted] The oxidation of alcohols to aldehydes and ketones using a sub-stoichiometric quantity of an oxoammonium salt bearing the nitrate counterion is reported. When the alcohol substrate is a liquid, the reaction can be performed solvent-free. When using a solid alcohol, the reaction can be performed either using a small volume of dichloromethane as a solvent, or else by leveraging mechanochemical activation. The methodology is applicable to the challenging oxidation of α-trifluoromethyl alcohols to the corresponding trifluoromethyl ketones. [ABSTRACT FROM AUTHOR]
