Arylboronic acid derivatives and preparation method thereof

Abstract

The invention provides arylboronic acid derivatives and a preparation method thereof. The two arylboronic acid derivatives are tri(4,4',4'-triboric acid-phenyl)amino(3BzN-3B) and tri(4,4',4'-triboric acid-phenyl)boron(3BzB-3B), and the molecular structures are as shown in the specification. 3BzN-3B and 3BzB-3B are prepared by firstly, respectively reacting tri(4,4',4'-triboric acid-phenyl)amino and tri(4,4',4'-triboric acid-phenyl)boron with n-butyllithium, secondly, respectively carrying out nucleophilic substitution reaction with boric acid ester, and finally carrying out acidolysis by using diluted hydrochloric acid. The products of the arylboronic acid derivatives, namely, the 3BzN-3B and the 3BzB-3B are expected to be excellent environment-friendly organic fire retardants.

Description

technical field

[0001] The invention relates to the technical field of flame retardancy of organic polymer materials, in particular to arylboronic acid derivatives and a preparation method thereof. Background technique

[0002] With the development of modern science and technology, polymer materials have played a huge role in the national economy and people's lives. Due to the flammability of polymer materials, fire accidents have increasingly become a social issue of concern to people, so flame retardants continue to develop with the development of polymer materials. As the most active field of flame retardants, organic flame retardants have a wide variety, including halogenated flame retardants, organophosphorus flame retardants, etc., but because of their shortcomings such as large smoke generation, high toxicity, and poor thermal stability , so it is imperative to seek new flame retardants.

[0003] In view of the fact that boronic acid derivatives are a class of excel...
