Abstract We report a novel metal‐free approach for the desulfonylative halogenation of aryl sulfonyl chlorides and C‐H arenes. This strategy employs hypervalent iodine(III) as both an oxidant group transfer agent with tetrabutylammonium halides (TBAX) halide source. The method offers several key benefits, including use inexpensive readily available reagents, simple reaction conditions, compatibility air, absence transition metals.

The development of environmentally friendly and efficient protocol for the synthesis heterocyclic compounds is current demand synthetic community. Solvent-free has emerged as a sustainable approach reducing waste generation, minimizing environmental impact. In this connection, we have developed solvent-free method construction five membered heterocycles i.e. isoxazoline pyrazoline from α, β-unsaturated carbonyl Hydrazine/hydroxylamine hydrochloride. This involves [3+2] cycloaddition reaction...

Developed using web technologies robust API integration, proposed solution empowers brands marketers to streamline their online presence,...

Abstract A series of benzo[ a ]chromeno[2,3‐ c ]phenazine derivatives were synthesized through an efficient one‐pot, multicomponent eco‐friendly reaction 2‐hydroxynaphthalene‐1,4‐dione, o ‐phenylenediamines, cyclic 1,3‐dicarbonyl compounds and aromatic aldehydes, promoted by glycerol. To the best our knowledge this is first catalyst free protocol for synthesis important scaffold having potential applications in medicinal materials chemistry. Other attributes present method are use glycerol...

Fly ash (FA)-based geopolymer was prepared using sodium hydroxide and silicate (in 2.5ratio) as an alkali activator liquid (AL). The condition of FA/AL optimized for achieving 1.00, 1.25, 1.5, 1.75 ratios by varying the concentrations, which are referred to GP1, GP2, GP3, GP4, respectively. influence slight variations in ratio on microstructure, morphology, functional groups, composition investigated X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fluorescence...

Mild steel is used as main raw material in fabrication of equipment, chief construction and weapons. During the storage transportation conditions, it comes contact with aggressive environment which leads to decrease mechanical strength. Four different vapor phase corrosion inhibitors (VPCIs) i.e. N-N-Dimethyl aniline (DMA), Morpholine, Cyclohexyl amine Hexamethylene imine were tested for mild under corrosive atmospheric conditions at 40°C by Weight Loss, Eschke test, Salt Spray SEM...

Developmental changes and effects of various abiotic stresses on peptidyl prolyl cis-trans isomerase (PPIase) activity were studied in the seedlings sorghum [Sorghum bicolor (L.) Moench cv. CSH-6]. The PPIase markedly decreased after two days germination. Up to 90 % was inhibited by cyclosporin-A. Maximal increase specific 3-d-old observed response osmotic stress it transient nature. stress-induced enhancement activity, depending upon tissue treatment, due induction cyclophilins as well...

: A practical and novel approach for the regioselective synthesis of 3-arylthioindole derivatives has been accomplished using a combination indole substrates with p-toluene sulfonyl hydrazide. This methodology employs NIS as oxidant PPh3 reductant to give desired 3-arylthioindoles in good excellent yields. method offers several advantages, including simplicity, operational ease, broad substrate scope.

An eco-compatible, facile and clean strategy for the synthesis of 1, 4-dihydropyridine (1, 4-DHP) derivatives has been reported through one pot multi-component Hantzsch reaction using glycerol as a promoting medium. A nontoxic cheap by-product biodiesel industry i.e., utilized condition in our protocol. The protocol offers greener, economical expeditious biologically significant 4-DHPs with moderate to excellent yields high atom economy under metal free mild conditions. In addition,...

Mild steel is widely used as main raw material in fabrication of equipment, chief construction and weapons. During its storage transportation conditions, it comes contact with aggressive environment which leads to decrease mechanical strength loss useful properties. Four different vapor phase corrosion inhibitors (VPCIs) i.e. Benzaimidazole (BIA), Diphenyl amine (DPA), 2-mercapto benzothiazole (MBTA) N,N-dimethyl aniline (DMA) were tested under atmospheric conditions at 40 °C by Weight Loss,...

Heterosis breeding is a potential tool to achieve improvement in quantity, quality and productivity pumpkin. An investigation was carried out study the heterosis combining ability for earliness yield characters of 28 hybrids pumpkin (Cucurbita moschata Duch. ex Poir.) through diallel mating design excluding reciprocals. Evaluation parents based on per se general (gca) effects revealed that Narendra Agrim, Kashi Harit, Punjab Samrat Pusa Vishwas were identified as donors characters. Among...
