Architectural photocatalysts have considered to be an eco-friendly and green technology for protection and remediation of environment and the emergence of these photocatalysts also provides a new way for solar energy conversion and utilization as it only works under sunlight irradiation. Based on latest research from related group and other colleagues, this paper mainly reviews the different synthesis of architectural pho Read More

Background: The conception of ‘Green chemistry’ is the much inventive chemistry which is potent and more environmentally benign. It is notable that many organic reactions take place in conventional organic solvents, known as volatile organic compounds. Being concerned about the environmental impact, we report a promoting medium, coconut juice (ACC) for one-pot synthesis of biscoumarins and pyranocoumarins Read More

Background: 4-Arylmethylideneisoxazol-5(4H)-ones are a class of organic compounds with a variety of applications in the agriculture, filter dyes, photonic devices, and pharmaceutical industries. They are also used as synthetic precursors for the synthesis of other organic compounds. As a result, efforts are being made to search new and available catalyst and green methods toward their synthesis. Objective: The aim of this Read More

Background: The AFM-techniques have been used for the research of the role of intermolecular H-bonds and stable supramolecular nanostructures, based on effective catalysts of oxidation processes, which are also models of Ni(Fe)ARD Dioxygenases, in mechanisms of catalysis. Methods and Results: The role of Histidine and Tyrosine ligands in the mechanisms of catalysis by FeARD on model systems is discussed Read More

Background: We are submitting an easy, effective and environmentally benign protocol for the synthesis of 18 different 1,2-dihydroquinazoline derivatives. Methods: We implemented [TMA][OH] ionic liquid mediated hydrotalcite clay catalytic system as a green catalyst to perform this reaction. Results: Three-component reaction pathway was utilized to synthesize 1,2-dihydroquinazoline derivatives using aromatic aldeh Read More

Background: ADA as N-(2-Acetemido) iminodiacetic acid has been widely used in preparation of organic buffers and protein-free media for fibroblasts as chelating agent chicken embryo fibroblasts as tridentate chelating agent ligand. However, a little attention has been focused to the behavior of its oxidation in aqueous acidic solutions. Accordingly, a lack of information on the aqueous chemistry of oxidation of ADA in Read More

Background: This research introduces an effective and green method for the synthesis of polysubstituted 2-pyrrolidinone derivatives as biologically-active heterocyclic compounds using multi- component reactions using Fe3O4@L-arginine as a reusable organocatalyst. Material and Method: The Fe3O4@L-arginine nanoparticles were prepared by a facile one-step approach and the structure elucidation of the magnetic nanocataly Read More

Background: A green, recyclable and reusable chitosan catalyst has been utilized for the synthesis of 5-amino-2,3-dihydrobenzo[d]thiazole-4,6-dicarbonitrile and its derivatives. Methods and Results: Three-component reaction protocol incorporates the reaction of aldehydes, malononitrile and rhodanine derivatives. This is examined as an efficient route for the synthesis of dicarbonitriles utilizing a green, biodegradable, envi Read More
