富马酸单正烷基酯的合成和表征

摘要

Mono-ra-alkyl fumarate (3a ~3h)were synthesized by the alcoholysis of maleic anhydride (1) with C, ~ Cgn-alkyl alcohol (2a ~2h) , followed by the isomerization in the present of aluminium trichloride. The total yield of alcoholysis and isomerization was 79. 2% -87. 3%. The structures were confirmed by ESI-MS,'H NMR and IR.%马来酸酐(1)和C1～C8正烷基醇(2a ～2h)发生醇解反应生成马来酸单正烷基酯,后者接着在无水AlCl3存在下加热发生异构化反应,得到富马酸C1～C8单正烷基酯(3a～3h),醇解反应和异构化反应的总收率79.2％ ～ 87.3％.其结构经ESI-MS,IR和1H NMR表征.
