The ring transformation of 1,6-dimethyl-, 1,4-dimethyl- and 4-methoxy-1-methyl-3,5-dinitro-2-pyridones with sodio β-keto esters to nitrosalicylic esters was investigated concerning the electronic effects of 4 and 6-substituents. The results were explained by the HSAB principle.
研究了 1,6-二甲基-、1,4-二甲基-和 4-甲氧基-1-甲基-3,5-二硝基-2-吡啶酮与 sodio β-酮酯到亚硝基水杨酸酯的环转变过程中 4 和 6-取代基的电子效应。研究结果用 HSAB 原理进行了解释。
