Question

Phenyl boronic acid using triemthyl borate mechnism

Answer 1

Answer:

One of the most common synthesis uses phenylmagnesium bromide and trimethyl borate to form the ester PhB(OMe)2, which is then hydrolyzed to the product. Other routes to phenylboronic acid involve Electrophilic borates to trap phenylmetal intermediates from phenyl halides or from directed ortho-metalation.
