The Borazines,a ring structure of alternating boron arid nitrogen atoms and ever since, borazine, (—BH—NH—)., and its derivatives have attracted the interest of the chemist primarily because of the resemblance of the six-membered boron-nitrogen heterocycle to benzene and its derivatives. Indeed, a comparison of a

,-Bonded Cyclic Systems of Boron and Nitrogen (Other than Borazines),ree years. Examples of such compounds, however, are still very few. This discussion will be developed with respect to increasing ring size rather than irom a historical point of view and the “borine” nomenclature of the systems will be used. To date, derivatives of the following four rings are known

Heterocyclic ,-Bonded Systems Containing Boron and Nitrogen,tems, has been characterized through studies by Goubbau and coworkers.’ .. In 1955 they prepared 1,3,2-diazaboraeycloalkanes illustrating that it is possible to incorporate boron and nitrogen adjacent to each other in a B—N—C ring system in which all annular atoms are .-bonded to each other..
