Diboronic acids (HO)2B·R·B(OH)2(where R = polymethylene, arylene, or thiophen-2,5-diyl) are prepared by reactions of methyl borate with difunctional Grignard reagents and are characterised by the formation of cyclic esters with various diols. The polymethylenediboronic acids are much more resistant to aerial oxidation than are the corresponding alkylboronic acids. All the diboronic acids undergo dehydration
Résumés Français Anglais Nous avons synthétisé SubPcBCl à partir de l’acide 1,4-diboronique benzène avec un rendement de 45 %. Les analyses spectrométriques IR, UV-visible et RMN du proton sont conformes aux données de la littérature. SubPcBCl is synthesized from 1,4-benzene diboronic acid with a yield of 45%. The infrared, electronic and proton NMR spectra are in accordance with the results of literature.
