How to add phenyl group
NettetNumerous methods exist to synthesize phenylboronic acid. 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. [5] PhMgBr + B (OMe) 3 → PhB (OMe) 2 + MeOMgBr PhB (OMe) 2 + H 2 O → PhB (OH) 2 + MeOH NettetAs you can see, electrons from the phenyl ring can flow into the carboxylic acid group which gives the hybrid shown to the right. There are no resonance forms where electrons from the carboxylic acid are donated into the phenyl ring.

NettetThere's a wide variety of ways to do this. They generally require substituted aromatic rings (for example, aryl halides for Negishi or Ullmann reactions or an alkyl halide and a boronic acid in the Suzuki coupling), and some sort of inorganic catalyst (palladium (0) for Suzuki and others; zinc, nickel or copper for others).
