  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
