Syntheses and properties of cycloborazines and cyclocarborazines

We present a review of preparative methods as well as physico-chemical properties of selected types of cyclic boron–(carbon)–nitrogen containing compounds. The review is compiled as a synthetic manual for preparation of compounds with the desired structure, which are to be further modified to novel, as yet unknown derivatives.The compilation is subdivided according to various types of ring sizes. Each section presents known methods of synthesis of respective cyclo(car)borazines highlighting their possible functionalisation. The important data on hydrolytic stability of compounds are also included.

Graphical abstractThe brief review evaluates known synthetic methods of cyclic borazines and cyclocarborazines and summarises their important physico-chemical properties. It is compiled as a guide for the targeted preparation of various classes of respective compounds. The review also includes useful data on hydrolytic stability of cyclo(car)borazines.Figure optionsDownload full-size imageDownload as PowerPoint slide
