    • Derivatives of perbromic acid of the formula: XBrO.sub.4 wherein X is Ag, H.sub.3).sub.2 CH, or (CH.sub.3).sub.2 C.sub.2 H.sub.3 prepared by a synthesis of silver perbromate through the reaction of dilute aqueous perbromic acid with silver oxide at a temperature from 0.degree. to 50.degree. C, followed by a removal of water and by a synthesis of isopropyl or isobutyl perbromate through the reaction of anhydrous silver perbromate suspended in a fluid selected from the class consisting of carbon tetrachloride, cyclohexane, and 1,1,2-trichlorotrifluoroethane with an alkyl bromide at a temperature from -25.degree. to 0.degree. C. Isopropyl and isobutyl perbromates are useful as oxidizing agents for alcohols.
    • 通式为:XBrO4的过溴酸衍生物,其中X为Ag,(CH 3)2 CH或(CH 3)2 C 2 H 3),其通过在0℃至50℃的温度下通过稀水溶液与氧化银的反应合成过溴酸银制备 然后除去水,并通过悬浮在选自四氯化碳,环己烷和1,1,2-三氯三氟乙烷的流体中的无水过溴化银反应合成异丙基或异丁基溴化铵, 烷基溴在-25℃至0℃的温度下进行。异丙基和异丁基过溴酸盐可用作醇的氧化剂。
