“…The deamination of aromatic amines is a widely used process in the chemical industry [ 12 ]. Despite the fact that there are a variety of deamination processes, deamination of aromatic amines normally involves activating the amino group by diazotization, followed by the replacement of the diazo group with hydrogen [ 13 – 15 ].…”

In pristine graphitic carbon nitride (g-CN), amino groups often function as structural defects that trap photogenerated charges, resulting in low photocatalytic activity as well as reaction with nitrite, aldehyde, etc., ensuing in poor product yield. Without significantly altering the optical characteristics, the removal of amino groups is necessary to increase the photocatalytic activity and structural stability of pristine g-CN. The deamino graphitic carbon nitride ( DA-gCN-5 ) was prepared by tert -butyl nitrite (TBN)-treatment, characterized and used as a photocatalyst for the radical C-H arylation of heteroarenes using anilines as radical source. Indeed, the photophysical characteristics of DA-gCN-5 and those of pristine g-CN are very comparable, except that DA-gCN-5 has a fewer residual amino groups, higher crystallinity, and compressed structure with a different morphology. Moreover, DA-gCN-5 -catalyzed C-H arylation reaction offers greater product yield in a shorter reaction time compared to that of pristine g-CN in the coupling between heteroarenes and the in situ generated aryl diazonium salts from anilines under visible light irradiation. The amino groups in pristine g-CN absorbed the TBN that was added to convert aniline into the appropriate diazonium ions during the reaction. As a result, deamino graphitic carbon nitride produced by chemical treatment has better photophysical properties and catalytic activity than pristine g-CN. Additionally, this is the first method that uses diazotization reaction for the preparation of deamino graphitic carbon nitride, as far as we are aware.

Using renewable resources to produce valuable chemical products is an alternative to traditional processes based on petrochemical synthesis. The review focuses on the main approaches associated with the production of organic acids from glucose and cellulose as the components of renewable biomass. It covers a comparison of biotechnological approaches for the production of glycolic, glutaric, mesaconic, muconic, isobutyric, lactic, 3-hydroxypropionic, succinic, itaconic and adipic acids with catalytic approaches. It was shown that the biotechnological production of succinic and lactic acids has been applied on an industrial scale, and that a number of other organic acids can be produced using fermentation if more productive strains will be used.
