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]

“…Recently, several environmentally friendly methods have been reported to avoid the use of potentially toxic metal-catalysts. [18][19] However, in most cases, longer reaction times and complex reaction systems were necessary. Herein, we report a catalyst-free condition for the transformation of aryl boronic acids to substituted phenols by using H2O2 as oxidant and solvent.…”

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.

“…The synthesis of phenols has received much attention in recent studies because of its importance as a starting material and structural constituent of pharmaceuticals, polymers, versatile intermediate building blocks [14] and natural products [15][16][17]. Mulakayala et al reported the preparation of phenols from aryl boronic acids by treatment with hydrogen peroxide in the presence of Amberlite IR-120 resin; the reaction was conducted at room temperature in the absence of an organic solvent [18].…”

Oxidative reactions often require unstable and environmentally harmful oxidants; therefore, the investigation of safer alternatives is urgent. Here, the hydroxylation of aryl boronic acid in the presence of Co-complexes is demonstrated. Tetrakis(4-carboxyphenyl) Co(II)-porphyrin was combined with biodegradable polymers such as chitosan catalyzed hydroxylation of phenyl boronic acids to form phenol derivatives under blue-light irradiation. This catalytic system can be used as an eco-friendly oxidation process that does not release oxidizing agents into the atmosphere.
