“…Recently, the biosynthesis of metal nanoparticles (MNPs) have been proposed as a cost-effective and eco-friendly substitute to chemical methods. Many studies have been demonstrated the biosynthesis of AgNPs mediated by the microorganism or by phytochemicals or enzymatic synthesis [11,18,19,[29][30][31][32][33]. Among the biological methods, photosynthesis which involves reduction by phytochemicals derived from plants seems to be the superior choice.…”

In this study, highly monodispersed, exceptionally stable, spherical silver nanoparticles (AgNPs) were successfully synthesized by the microwave assisted rapid and cost-effective green method. Aqueous extract of clammy cherry (Cordia obliqua Willd) fruit was used as the green reductant, and capping agent for the synthesis of AgNPs and the effect of different synthesis parameters on the optical properties of the synthesized AgNPs was also studied. The characterization of synthesized AgNPs by Fourier transform infrared spectroscopy, X-ray diffraction studies, UV-visible spectroscopy, scanning electron microscopy and transmission electron microscopy (TEM) revealed the formation of small AgNPs with narrow size distribution. TEM studies corroborated that the AgNPs are highly crystalline and spherical with an average diameter of 7.13 nm. The cyclic voltammetry profile of AgNPs modified electrode in NaOH depicted prominent redox peaks evidencing an impressive electrochemical response. The AgNPs manifested high catalytic activity towards reduction of methyl orange and rhodamine blue with apparent rate constant 0.3038 min −1 and 0.1542 min −1 respectively. Additionally, the prepared AgNPs exhibited strong antibacterial efficacy against the tested microbes.

A catalyst-free and solvent-free method for the oxidative hydroxylation of aryl boronic acids to corresponding phenols with hydrogen peroxide as the oxidizing agent was developed. The reactions could be performed under green condition at room temperature within very short reaction time. 99% yield of phenol could be achieved in only 1 min. A series of different arenes substituted aryl boronic acids were further carried out in the hydroxylation reaction with excellent yield. It was worth nothing that the reaction could completed within 1 min in all cases in the presence of ethanol as co-solvent.

“…In 2018, Karak and co‐workers prepared a hyperbranched polyurethane‐supported Pd‐Ag@CQD nanocomposite, which displayed exceptional efficiency as a robust and recyclable catalyst for rapid oxidative hydroxylation of aryl boronic acids to form corresponding phenols (Scheme g) . At the same time, Chatterjee and co‐workers prepared Ag nanoparticles for hydroxylation reaction of aryl boronic acids (Scheme h) . The reaction was conducted under environmentally benign medium at the bio‐nano interface using 30 % aqueous H 2 O 2 as oxidant.…”

Phenol and its derivatives are fundamental building blocks in organic synthesis and materials science. Over the past decades, tremendous attention has been paid to construct functionalized phenols, and various methods have been developed. Owing to the high efficiency and mild reaction conditions, synthesis of phenols from the hydroxylation of aryl boronic compounds has been emerging as a promising approach. In this review, we summarize the progress using aryl boronic compounds as starting reagents to synthesize phenol deriva- [a]
