method. The combination of [WZn3(H2O)2(ZnW9O34)2]12− and Co(II) provides a synergistical catalytic way to promote oximation of aldehyde/ketone with in situgenerated hydroxylamine that initially produces an oxime, which further either dehydrates into a nitrile or undergoes a Beckmann rearrangement to form an amide.
通过水热法制备亲水性无机多孔催化剂。[WZn 3(H 2 O)2(ZnW 9 O 34)2 ] 12-和Co(II)的组合提供了一种协同催化方式,以促进醛/酮与原位生成肟的羟胺肟化,其进一步脱水成腈或经历贝克曼重排以形成酰胺。
Synthesis, photophysical and acidochromic properties of a series of tetrahydrodibenzo[a,i]phenanthridine chromophores
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。
