  • Hypoiodite reaction: the decomposition of oxalic acid half-esters
    作者:K. Bartel、A. Goosen、A. Scheffer
    DOI:10.1039/j39710003766
    日期:——
    Alkyl half-esters of oxalic acid photolysed with mercury(II) oxide–iodine reagent gave mainly dialkyl oxalates. 1-Apocamphyl hydrogen oxalate gave, in addition to the diester, 1-apocamphyl iodide. 9-Triptycyl hydrogen oxalate gave 9-triptycyl iodoformate, which was thermally decomposed to 9-iodotriptycene and with silver tetrafluoroborate gave 9-triptycyl fluoroformate. We suggest that diester formation
    草酸的烷基半酯与氧化汞(II)-碘试剂光解后,生成的主要是草酸二烷基酯。除二酯外,1-阿朴茶酸草酸氢盐还产生了1-阿朴茶酸碘化物。9-三苯甲基草酸氢酯产生9-三苯甲基碘甲酸酯,将其热分解成9-碘三苯并噻吩,并与四氟硼酸银一起产生9-三苯甲基氟甲酸酯。我们建议通过中间烷氧基羰基基团的偶联发生二酯形成。
  • Thermal decomposition of oxalate diesters in the presence of iodine
    作者:A. Goosen、A. Scheffer
    DOI:10.1039/p19720000369
    日期:——
    Dialkyl oxalates decomposed in the presence of iodine at temperatures at which the pure diesters were stable. Dioctadecanyl, dicyclohexyl, and di-1-adamantyl oxalate gave the corresponding iodides, whereas dibenzyl oxalate gave diphenylmethane. The mechanism of the iodine-induced decomposition of dialkyl oxalates is discussed.
    草酸二烷基酯在碘存在下在纯二酯稳定的温度下分解。草酸二十八烷基酯,二环己基酯和草酸二-1-金刚烷基酯生成相应的碘化物,草酸二苄基酯生成二苯基甲烷。讨论了碘诱导草酸二烷基酯分解的机理。
