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

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
