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。
