Methods are disclosed for converting a carboxylic acid by using a diboron reagent to convert the carboxylic acid or imide ester derivative of a carboxylic acid to a boronic ester. The method may involve providing an imide ester, such as a phthalimide ester, of a carboxylic acid, and treating the imide ester with a diboron reagent, thereby forming a boronic ester. The diboron reagent may be selected from bis(catecholato)diboron, B2(OH)4 or a mixture thereof, optionally in the presence of catechol.
