Phenylboronic acid reagents of General Formula IX are prepared by condensation of (3-aminophenyl)boronic acid with an activated dicarboxylic acid preferably selected from, but not limited to, either succinyl chloride, adipoyl chloride, adiptic acid diisobutylcarbonate, suberoyl chloride,3,3'-dithiopropionyl chloride and 3,6,9-trioxaundecanedioyl chloride and 3,6,9-trioxaundecanedioic acid diisobutylcarbonate. The preparation of a single reagent of General Formula IX has been previously reported (Burnett, T. J., Peebles, H. C. and Hageman, J. H. (1980) Biochem. Biophys. Research Commun., 96, 157-162). ##STR11##
