Polymer-supported bromate ion oxidizer was prepared from strong basic ion-exchange resin with sodium bromate. In the presence of 40% HBr or AlCl~3 or NaHSO~3, the primary alcohols and simple ethers were readily oxidized to esters; secondary alcohols to ketones; α, ω- diols and cyclic thers to lactones; thoils and selenols to the corresponding disulfides and diselenides with good to excellient yields respectively, by the polymer-supported bromate ion oxidizer.
