1H-Benzimidazole-5-boronic acid, picol ester - Introduction

Acol ester is an organic compound with the chemical formula C14H18BNO2.

Properties: acid, pinacol ester is a solid with a white to yellowish color. It is almost insoluble in water at normal temperature, but soluble in some organic solvents such as dimethyl sulfoxide and acetonitrile. It is a stable compound that can be stored and handled under regular experimental conditions.

use: acid, pinacol ester is widely used in organic synthesis. It is an important Organoboron reagent that can be used to catalyze coupling reactions, such as Suzuki coupling reaction and Negishi coupling reaction. These reactions are of great significance for the synthesis of complex organic molecules, so pinacol ester has been widely used in the fields of drug synthesis, material science and pesticide research and development.

Preparation method: The common synthesis method is to react 1H-benzimidazole and diborate in an appropriate solvent. Usually, the reaction is carried out under an inert gas to avoid reaction with oxygen and moisture in the air.

Safety information: acid, pinacol ester has low toxicity and danger under regular operating conditions. However, like all organic compounds, it should be stored and handled under properly ventilated conditions, avoiding inhalation and contact with skin and eyes. Appropriate personal protective equipment, such as lab gloves and goggles, should be worn during use.
