Summary: In this study, a liquid-assisted mechanochemical route mediated by 1,3-dimethylbarbituric acid-H2O was developed for the synthesis of a wide array of 5-aryl/spiro-1,2,4-triazolidine-3-thiones. The method is efficient, easy to follow, and avoids the tedious steps of catalyst preparation and chromatographic separation. The protocol was compared to an on-water, room temperature approach and the reaction mechanism was revisited through experiments.

Summary: This study reports the divergent synthesis of two different classes of azole derivatives using 5-amino-substituted 2-methoxy-1,3,4-oxadiazoles as common substrates. Depending on the reaction time and temperature, alkylation of oxadiazoles with excess alkyl halides proceeds with high regioselectivity toward 1,3,4-oxadiazolones and 1,2,4-triazolidine-3,5-diones. This operationally simple protocol enables rapid access to a diverse set of isomeric azoles using minimum synthetic steps and easily accessible oxadiazole key precursors.

Summary: First-time cobalt chromite nanoparticles were synthesized using honey as a natural precursor through a bio-derived approach. The as-synthesized nanoparticles exhibited a cuboidal topology with an average size of 31.69 nm. These nanoparticles were used as a catalyst for the facile formation of 5-aryl-[1,2,4]-triazolidine-3-thiones. The study highlights the potential of synthesize cobalt chromite nanoparticles using a green approach in nanochemistry research.

Summary: This paper describes the synthesis of polyindole using copper chloride as an oxidant and its characterization using various spectroscopic techniques. The polyindole was found to have a semi-crystalline nature through XRD analysis. A solvent-free, ultrasound-assisted synthesis of biologically active DHPM derivatives using polyindole as a recyclable catalyst was reported, showing advantages of mild reaction conditions, short reaction time, high yields, and low catalyst loading. Factors affecting the reaction rate, such as ultrasonication, temperature, solvent, catalyst amount, and recyclability, were also studied.
