本文研究以石油砜作为非质子极性溶剂的可能性。以2-甲基-4-氯-2-丁烯与丙酮作用合成6-甲基-5-庚烯-2-酮(Ⅰ)为例进行探荣。结果表明,有石油砜存在时,产品得率由27%提高到53%,如再加少量水和相转移催化剂,Ⅰ的得率为62%,与使用环丁砜为溶剂时所得收率相同。 This article investigates the possibility of using petroleum sulfone as the aprotic polar solvent. The 2-methyl-4-chloro-2-butene and acetone synthesis of 6-methyl-5-hepten-2-one (Ⅰ) as an example of Prosperous. The results showed that in the presence of petroleum sulfoxide, the yield of the product increased from 27% to 53%. For example, with a small amount of water and a phase transfer catalyst, the yield of Ⅰ was 62%, which was the same as the yield obtained with sulfolane.
