Controlling the pH value by changing the negative ion of ionic liquids, the same reactions of aromatic aldehyde, 2‐(2,3‐dihydrothiochromen‐4‐ylidene) malononitrile and malononitrile product unaromatized and aromatized 6H‐benzo[c]thiochromene derivatives in high yields. The nice features of these procedures include mild reactions condition, simple operations, high yields, and environmentally benign
通过改变离子液体的负离子来控制pH值,芳香醛,2-(2,3-二氢硫代色素-4-亚基)丙二腈和丙二腈产品未经芳构化和芳构化的6 H苯并[ c ]硫代苯醌衍生物的相同反应高产。这些程序的优点包括反应条件温和,操作简单,产率高以及对环境无害。J.杂环化学。(2011)。
