摘　　要：在30%双氧水和醇组成体系中,聚合物负载的苯亚硒酸试剂可有效地促进过氧化氢氧化肟转变成羧酸酯;相应伯醇和仲醇的羧酸酯的产率中等到良好,但在含叔醇的体系中没有相应的羧酸酯生成.聚合物负载的苯亚硒酸试剂无需处理即可循环使用,其活性无明显下降.Aromatic and aliphatic aldoximes could be efficiently converted into the corresponding carboxylic acid esters by treatment aldoximes with an alcoholic solution of 30% hydrogen peroxide in the presence of catalytic amounts of polystyrene-bound phenylseleninic acid. Primary and secondary alcohols give moderate to good yields, but with tertiary alcohols no esterification was observed. The recovered phenylseleninic acid resin could be in subsequent used with no further treatment and no significant loss of reactivity.
