Synthesis of 2,3-Disubstituted Quinazolinone Derivatives Using Silver Triflate as a Efficient Catalyst at Room Temperature

European Reviews of Chemical Research, 2017, 4(1): 4-12.
DOI: 10.13187/ercr.2017.1.4CrossRef

Heterocyclic compounds are commonly used Scaffolds on which pharmacophores are arranged to provide potent and selective drugs. This is especially true for Nitrogen containing hetero cycles, which serve as the core components of many substances that possess a wide range of interesting biological activities. A series of 2,3-disubstituted quinazolinone derivatives have been synthesized in excellent yields at room temperature. The reaction was efficiently promoted by AgoTf. This protocol is very simple and provides moderate yields. All the products were identified by spectral (1H NMR, 13C NMR and mass) and analytical data.

Chemical Bath Deposition and Study of Semiconductor Thin Films in Cu2S−In2S3 System

European Reviews of Chemical Research, 2017, 4(1): 13-20.
DOI: 10.13187/ercr.2017.1.13CrossRef

In the first time thin films of InxCu1−xSyO1−y composition with the content of indium up to 9.63 at% were obtained by means of a chemical bath deposition from a system “indium chloride − copper chloride − sodium hydroxide − thiourea” and “indium chloride − copper chloride − sodium hydroxide – trilon B − thiourea”. The experimental date on the distribution and the atomic ration of elements in synthesized patterns obtained by the x-ray photoelectron spectroscopy were discussed. The change in the surface microstructure of thin films depending on the temperature and the composition of reaction bath were determined by means of scanning electron microscopy. The structure of obtained thin films has n-type of conductivity.

Theoretical Study of the Reactivity and Regioselectivity of the Addition Reaction between HCl and Alkenes, Investigation of the Markovnikov's Rule

European Reviews of Chemical Research, 2017, 4(1): 21-27.
DOI: 10.13187/ercr.2017.1.21CrossRef

A theoretical study of the mechanism and selectivity of the addition reactions between HCl and alkenes were performed using DFT B3LYP/6-31G(d). Analysis of the global electrophilicityindeces shows that the alkene 1-5 behaves as a nucleophile, while HCl behaves as an electrophile. in the addition reaction of the alkenes 1-5 with HCl, the most favorable electrophile-nucleophile interaction along will take place between the most nucleophile centre of alkenes 1-5, the less substituted carbon and most electrophilic centre of HCl, hydrogen atom, in clear agreement with Markovnikov's rule. The calculation of activation and reaction energies indicates that the formations of the Markovnikov’s products are favored both kinetically and thermodynamically.

Theoretical Investigation of the Chemo and the Regioselectivity of the Reaction Oxidation of Bicyclo[3.2.0]Hept-2-En-6-One by Hydrogen Peroxide

European Reviews of Chemical Research, 2017, 4(1): 28-33.
DOI: 10.13187/ercr.2017.1.28CrossRef

The mechanism, the chemoselectivity and regioselectivities of the oxidation reaction of bicyclo[3.2.0]hept-2-en-6-one and hydrogen peroxide, have been studied using B3LYP DFT methods together with the standard 6-31(d) basis set. The potential energy surface (PES) was analyzed by considering the chemo and regio-isomeric Pathways, we found that this reaction was chemo and regioselective and regioisomer P1 is kinetically and thermodynamically favored in good agreement with experimental Result, in addition the analysis of the potential electrostatic and Parr functions confirming this result.
