Popis

General description

Phenylboronic acid, pinacol ester, also known as boronate ester, is generally used in metal-catalyzed C-C bond formation reactions like Suzuki–Miyaura reaction.

Application

Phenylboronic acid pinacol ester can be used:

• To prepare sulfinamide derivatives by reacting with diethylaminosulfur trifluoride (DAST) and potassium phenyltrifluoroborate.
• As a substrate in the study of Suzuki–Miyaura coupling of various aryl iodides over SiliaCat Pd(0).
