Silver(I)-catalyzed sequential hydroamination and Prins type cyclization for the synthesis of fused benzo--sultams

03-Jul-2018 | B. Maheshwar Rao; J. S. Yadav; B. Sridhar; B. V. Subba Reddy, Organic & Biomolecular Chemistry, 2018

An intramolecular annulation strategy has been developed for the synthesis of tetrahydrobenzo[e]pyrano[4,3-c][1,2]thiazine derivatives by means of coupling of aldehydes with 2-(4-hydroxybut-1-yn-1-yl)-N-arylsulfonamides using a catalytic amount of silver hexafluoroantimonate in toluene at 80 °C. ...

Ab-initio design of light absorption through silver atomic clusters decoration of TiO2

03-Jul-2018 | María Pilar de Lara-Castells; Carlos Cabrillo; David A. Micha; Alexander Mitrushchenkov; Tijo Vazhappilly, Physical Chemistry Chemical Physics, 2018

A first-principle study of the stability and optical response of subnanometer silver clusters Agnn (n ≤5) on a TiO2(110) surface is presented. First, the adequacy of the vdW-corrected DFT-D3 approach is assessed using the domain-based pair natural orbital correlation approach DLPNO-CCSD(T) along ...

Silver nanoparticle embedded copper oxide as an efficient core–shell for the catalytic reduction of 4-nitrophenol and antibacterial activity improvement

03-Jul-2018 | N. Bouazizi; J. Vieillard; P. Thebault; F. Desriac; T. Clamens; R. Bargougui; N. Couvrat; O. Thoumire; N. Brun; G. L ..., Dalton Transactions, 2018

A facile and eco-friendly method was developed to prepare a microporous CuO@Ag0 core–shell with high catalytic and antibacterial activities. Scanning and transmission electron microscopy revealed a preponderance of nearly spherical 50 nm particles with slight structure compaction. Comparison of ...

Nanosized silver bromide: An efficient catalyst for alcohol oxidation in the presence of a multinuclear silver complex

20-Jun-2018 | Zahra Zand; Mohammad Mahdi Najafpour; Robabeh Bagheri; Zhenlun Song, New Journal of Chemistry, 2018

Investigating on a silver-based complex for the alcohol –oxidation reaction, we find AgBr as a new and considerable catalyst for the reaction in the presence of Oxone (2KHSO5.KHSO4.K2SO4). The catalyst was characterized by scanning electron microscopy, energy dispersive spectrometry, transmission ...

Plant extracts as green reductants for the synthesis of silver nanoparticles: Lessons from chemical synthesis

20-Jun-2018 | Muhammad Nawaz Nawaz Tahir; Mujeeb Khan; Mohammed Rafi Shaik; Syed Farooq Adil; Shams T. Khan; Abdulrahman Abdullah ..., Dalton Transactions, 2018

The increasing use of silver (Ag) nanoparticles (NPs) in daily-life applications, elec-tronics, or catalysis calls for green and cost-efficient synthetic methods. Ag NPs are used especially in biomedicine because of their antibacterial, antifungal or anticancer properties. The chemical synthesis ...

Assembly of silver-oxo complexes based on N-diphenylphosphanylmethyl-3-aminopyridine and their structures, photocatalysis and photocurrent responses

20-Jun-2018 | Lin-Yan Xu; Wei Yang; Chao-Fan Liu; Zhi-Gang Ren; Jian-Ping Lang, CrystEngComm, 2018

A new P-N hybrid ligand N-diphenylphosphanylmethyl-3-aminopyridine (3-dppmapy) is synthesized and allowed to react with six silver oxysalts including AgTFA (TFA = trifluoroacetic), AgOTF (OTF = trifluoromethanesulfonic), AgNO3, Ag2SO4, AgBz (Bz = benzoate) and AgSal (Sal = salicylate). The ...

How Interface Compatibility Affects Conductivity Evolution of Silver Nanobelts-filled Electrically Conductive Composites During Cure and Post-Treatments

20-Jun-2018 | Geoffrey Rivers; Pearl Lee-Sullivan; Boxin Zhao, Physical Chemistry Chemical Physics, 2018

Using silver nanobelts and silver microflakes in a DGEBA/TETA epoxy matrix, we sought to investigate the relationship between the evolving electrical resistivity of formulations of hybrid nanocomposites during the curing process. This was characterized using three methods: (i) in-situ four-wire ...

Solvent effects on the crystal structure of silver pentacyanocyclopentadienide: supramolecular isomerism and solvent coordination

20-Jun-2018 | P. R. Nimax; D. Reimann; K. Sünkel, Dalton Transactions, 2018

Several coordination polymers of silver(i)–pentacyanocyclopentadienide (PCC) were studied by X-ray diffraction to examine the effects of different solvents on supramolecular isomerism of the PCC-ligand. While alcohols yield supramolecular isomers of [Ag(PCC)] without coordination of solvent ...
