    • A solid oxidizing agent is provided to increase the reaction rate when oxidizing the alcohol having long alkyl chain difficult to oxidize and the alcohol having low reaction rate, and to be selectively used for alcohol oxidation reaction without the influence on a functional group. A method for preparing porous crosslinked polystyrene supporter of the formula (I) bonded with 2-iodoxybenzamide comprises (i) a step for bonding 2-iodoxybenzamide to the porous cross-linking polystyrene supporter by reacting 2-iodobenzoic acid with porous crosslinked polystyrene resin induced with linear C1-5 alkylamino group or amine group; and (ii) a step of oxidizing 2-iodoxybenzamide bonded to the polystyrene resin. In the chemical formula (I), P is linear (CH2)n, wherein n is an integer of 0-5; Q is linear or branched (CH2)m, wherein m is an integer of 1-10; and MPS shows macroporous crosslinked polystyrene.
    • 提供固体氧化剂以在氧化长烷基链难以氧化的醇和反应速率低的醇时提高反应速率,并且可以选择性地用于醇氧化反应而不影响官能团。 制备与2-碘氧基苯甲酰胺结合的式(I)的多孔交联聚苯乙烯支撑体的方法包括:(i)2-碘苯甲酰胺与多孔交联聚苯乙烯树脂的反应,将2-碘苯甲酰胺与多孔交联聚苯乙烯载体结合的步骤 具有直链C 1-5烷基氨基或胺基; 和(ii)氧化与聚苯乙烯树脂结合的2-碘氧基苯甲酰胺的步骤。 在化学式(I)中,P为直链(CH2)n,其中n为0-5的整数; Q是直链或支链(CH2)m,其中m是1-10的整数; MPS显示大孔交联聚苯乙烯。
