Abstract
Zeolite-supported inorganic nucleophilic reagents were prepared by impregnation with their aqueous solutions, followed by calcination, and applied to several liquid-phase organic reactions. The reaction between alkyl bromides and potassium chromate was promoted by zeolites to give aldehydes, although residual water adsorbed on the zeolites caused unfavorable hydrolysis reaction to give alcohols. Zeolites also accelerated the oxidation of alcohols with potassium dichromate and displacement reactions of alkyl bromides with alkali iodides. The product yields were dependent on the type of the zeolites and counter cations of the inorganic nucleophiles.
