Summary: C-H functionalization is a convenient and powerful tool in modern chemistry, but its harsh reaction conditions limit its use for modifying unstable substrates. Biomass-derived furan platform chemicals are promising organic molecules, but their sensitivity to acids, oxidants, and high temperatures hinders traditional methods of C-H functionalization. New catalytic methods are urgently needed to modify non-reactive furan cores and obtain materials with controlled properties.

Summary: In recent years, ABO(3) perovskite materials have been widely used in heterogeneous advanced oxidation processes (AOPs) for water treatment and disinfection due to their remarkable catalytic properties. This review provides an overview of the synthesis strategies, structure, and properties of ABO(3) materials, and discusses their recent applications in various AOPs, including photocatalysis, Fenton/photo-Fenton, persulphate activation, sonocatalysis/sonophotocatalysis, catalytic/photocatalytic ozonation, piezocatalysis/piezo photocatalysis, and photoelectrocatalytic oxidation. The catalytic activity of ABO(3) perovskites can be modulated through synthesis protocol, doping, heterojunction formation, and the incorporation of carbon nanomaterials. Moreover, the combination of ABO(3) materials with oxidants such as persulphate, H2O2, and O-3 enhances the activity of hybrid processes. The review also discusses the mechanisms of charge carriers' formation and transfer in ABO(3-)mediated AOPs.

Summary: This study reports the synthesis of the first Ni-based ZIFs and demonstrates their high potential as heterogeneous catalysts for the Suzuki-Miyaura cross-coupling reaction. The presence and arrangement of the carbonyl functional groups on the imidazole linker play a crucial role in completing the preferred octahedral coordination of nickel, providing a promising platform for the rational design of Ni-based ZIFs for a wide range of catalytic applications.

Summary: This study presents a visible-light-induced dehydrogenative [4+2] annulation of benzothioamides and alkynes using the metal-free heterogeneous photocatalyst graphitic carbon nitride (g-C3N4). The reaction proceeds smoothly under mild aerobic conditions and gives a variety of isothiochromenes in good yields. Detailed mechanistic studies reveal that g-C3N4 promotes the formation of a sulfur-centered radical under visible-light irradiation through a single electron transfer process.
