A new route to diesters of symmetrical octene-, decene-, and dodecenedioic acids was proposed. The ratio of the cis/trans-isomers was 1: 4. The synthesis involved oxidative splitting of five-, six-, and seven-membered cycloalkanones with hydrogen peroxide into the corresponding ω-alkenoic acids followed by esterification and metathesis over Re2O7/B2O3-Al2O3-SnMe4.
提出了一种制备对称辛烯、癸烯和十二烯二酸二酯的新途径。顺式/反式异构体的比例为 1:4。 合成过程包括使用过氧化氢将五元、六元和七元环烷酮氧化分解为相应的 ω-烯酸,然后在 Re2O7/B2O3 上进行酯化和复分解-Al2O3-SnMe4。
