alkaline hydrolysis of 1,2-diaryl-1H-4,5,6,7-tetrahydro-1,3-diazepines 1 are studied. Results are analyzed on the basis of Hammett and Swain-Lupton constants, finding good structure-basicity correlation when both, inductive and mesomeric effects, are considered together. Regioselectivity is observed in the alkaline hydrolysis of compounds 1, and it is analyzed in light of the stereoelectronic control
研究了1,2-二芳基-1 H -4,5,6,7-四氢-1,3-二氮杂卓1的碱性和碱水解。在Hammett和Swain-Lupton常数的基础上对结果进行了分析,同时考虑了感应效应和介观效应时,发现了良好的结构-碱度相关性。在化合物1的碱性水解中观察到区域选择性,并根据立体电子控制理论对其进行分析。将结果与先前获得的五个和六个元环同系物的结果进行比较:分别为1 H -4、5-二氢咪唑和1,4,5,6-四氢吡啶亚胺。
