Abstract

The invention discloses a method of synthesizing an onium salt type condensation agent on the basis on the basis of a Willgerodt-Kindler reaction and a Vilsmeier-Haack-Arnold reaction. The method includes the steps of synthesizing a carboxylic acid compound through the Willgerodt-Kindler reaction with an acyl compound as a raw material; preparing a Vilsmeier-Haack-Arnold reagent; adding the carboxylic acid compound to the Vilsmeier-Haack-Arnold reagent to synthesize the onium salt type condensation agent. The method has reasonable synthesis route and stable and reliable process, is high in synthesis efficiency, can be used for producing the carboxylic acid compound and the onium salt type condensation agent at the same time, has great application prospect and huge commercial value and enriches types of inorganic and organic compounds and synthesis methods in inorganic and organic fields.

Description

technical field [0001] The invention relates to the synthesis of onium salt condensing agents, in particular to a method for synthesizing onium salt condensing agents based on Willgerodt-Kindler (WK) reaction and Vilsmeier-Haack-Arnold (VHA) reaction. Background technique [0002] Metal-organic porous materials (MOF) and covalent organic porous materials (COF) are two new types of porous materials that emerged at the end of the 20th century and the beginning of the 21st century. It has good applications in many fields such as transportation and electronic devices. In the design and synthesis process of MOF materials and COF materials, organic ligands are indispensable. There are many designs and choices of organic ligands. Relying on the mature organic synthesis technology, almost any organic ligands you want can be obtained to assemble different MOF materials and COF materials. With the support of strong synthetic chemistry, porous materials also have the ability to chang...
