It is commonly utilized in Suzuki coupling reactions to introduce phenylanthracene rings into conjugated materials, thereby altering their luminescence and structural properties. Additionally, it serves as an intermediate in the production of Organic Light-Emitting Diodes (OLEDs).

Synthesis

The conventional synthesis of 10-Phenylanthracene-9-boronic acid involves starting with 9-bromo-10-phenylanthracene. Under strong basic conditions, the bromine atom on the anthracene ring is removed to generate an aryl lithium reagent. This reagent is then reacted with trimethyl borate or triisopropyl borate, followed by hydrolysis to yield the boronic acid compound. This route is widely used and efficient for synthesizing arylboronic acids.

Safety Information

10-Phenylanthracene-9-boronic acid is classified as an irritant and may cause irritation to the skin and eyes. It is important to handle this compound with care, wearing appropriate protective gear such as gloves, goggles, and a face mask. In case of contact with skin or eyes, rinse thoroughly with water and seek medical attention if necessary. Furthermore, this compound belongs to aromatic organic compounds and poses a significant hazard to aquatic environments. It should not be allowed to enter underground water, waterways, or sewage systems in undiluted or large quantities.

Suppliers

Several suppliers offer 10-Phenylanthracene-9-boronic acid in various package sizes and at different prices. For instance, some suppliers offer 1 gram for approximately 10 yuan and 250 milligrams for about 68 yuan.
