This brief perspective outlines the pivotal role of Machine Learning methods in the green, digital transition of industrial chemistry. The focus on homogenous catalysis highlights the recent methodologies in the development of industrial processes, including the design of new catalysts and the enhancement of sustainable reaction conditions to lower production costs. We report several examples of Machine Learning assisted m Read More

Compounds with three membered rings experience greater strain than those with other ring systems. In general, the synthesis of small ring compounds, particularly three-membered molecules, faces major challenges because of the severe strain in this system. Moreover, microwaveassisted method creates a higher temperature due to the heat and radiation of a reaction mixture more rapidly than convent Read More

Aims: The study aims to synthesize oxadiazole, imidazole, benzimidazole, and cyclohexano analogues of 1, 5-benzodiazepines through phenoxyl/phenylamino linkage. Background: It is worthwhile to mention that imidazoles, benzimidazoles, oxadiazoles, are analysed extensively mainly as per their ready availability, broad chemical reactivity, and wide spectrum of biochemical activities, like antimicrobial, anti-infla Read More

Aims: Catalytic degradation of azo dye. Background: Azo dyes are toxic agents and pollutants, and the degradation of these dyes has an important application in the treatment of textile industry wastes.Catalytic decolorization of fast yellow dye by hexacyanoferrate (III), abbreviated as HCF(III) using polyvinylpyrrolidone abbreviated as PVP stabilized Ir-Ni bimetallic nanocrystals has been evaluated by kinetic spectrophotometric Read More

Background: Carbon-based materials, due to their unique properties such as lightweight, different forms, doping capability with hetero atoms, low cost, and ease of processability, are suitable support, for heterogeneous catalysts. Among them, cellulose, as one of the most abundant and renewable organic polymers, preserves a key position in many organic raw materials. Pyranopyrimidine derivatives, due to their high bio Read More

Aims: The aim of this study is to investigate the p-toluene sulphonic acid (p-Ts.OH)- catalyzed reaction of racemic-azetidine-2,3-diones with enantiomerically pure cis and trans-4- hydroxy-L-proline in refluxing ethanol culminating in a synthesis of substituted novel 3-(pyrrol-1- yl)-azetidin-2-ones at the C-3 position. Methods: This work describes an alternative synthetic route enabling the tandem transformation of proline to Read More

Background: Quinazolinones are a class of heterocyclic compounds that have a wide variety of applications. They are also used in agrochemicals. There are several methodologies reported for the synthesis of 2,3-dihydroquinazolines using various catalysts. Methods: Here, by using 1-butyl-1,2,4-triazolium as cation and trifluoroacetate as anion, 2,3- dihydroquinazolin-4(1H)-one has been synthesized. For the synthesis of 2,3- Read More
