A novel method for the preparation of N-chloroaldimines from commonly available aromatic aldehydes has been developed. The reaction proceeded effectively by two steps: aldehydes were initially transformed into imines and then chloro-substitution with NaClO2 gave the N-chloroaldimines. This simple protocol allows for the preparation of a variety of aromatic N-chloroaldimines in moderate to excellent
A series of luminescent 5-aryl-tetrahydrodibenzo[a,i]phenanthridines was developed through modified synthetic protocol using SnCl2-acetic acid as a catalyst. The synthesis was consistent with various functionalities and significantly improves the yields. These derivatives exhibit large molar absorption coefficients and higher Stokes shift values in the range 9739–2628 cm−1. The donor and acceptor groups
通过改良的合成方案,使用SnCl 2-乙酸作为催化剂,开发了一系列发光的5-芳基-四氢二苯并[a,i]菲啶。合成与各种功能一致,并显着提高了产率。这些衍生物在9739–2628 cm -1范围内显示出较大的摩尔吸收系数和较高的斯托克斯位移值。施主和受主基团显着诱导了电荷转移特性,从而导致在390–531 nm范围内具有中等量子产率的广泛发射特性。这些衍生物的质子化和季铵化研究表明,形成了一个新的红移吸收带,随后在发射中出现了增色效应,可以用作酸性变色传感器。
