Since A. W. Laubengayer's synthesis of B-trichloroborazine (1955), the practice of using high vacuum techniques has been partially supplanted by more classical approaches, and the utilization of spectroscopy as a tool for explaining both structures and mechanisms has been stimulated by the investigations of J. Goubeau and his school. New instrumental methods - for instance, the applications of NMR spectroscopy - have been found extremely helpful in exploring former postulations. Advances in preparation are illustrated by the fact that ten years ago some two dozen substituted borazines were known, whereas today more than two hundred such compounds have been described in the literature. Incorporation of the B-N grouping in aromatic nuclei gave access to a whole new area of boron-nitrogen derivatives and the interest of the theoretician has been attracted by the evolution of new and exciting structures and reactions. It is obvious from reading the symposium papers that a fruitful collaboration is developing in the area of boronnitrogen chemistry."

Boron-nitrogen compounds / Kurt Niedenzu

Public ISBD Titre : Boron-nitrogen compounds Type de document : texte imprimé Auteurs : Kurt Niedenzu ; John W. Dawson Editeur : Berlin : Springer Année de publication : 1965 Collection : Anorganische und Allgemeine Chemie in Einzeldarstellungen num. 6 Importance : viii, 175 p. Format : 24 cm ISBN/ISSN/EAN : 978-3-642-85828-4 Langues : Anglais (eng) Catégories : Chimie organique Tags : BORON COMPOUNDS  NITROGEN COMPOUNDS Index. décimale : B-C Résumé : "Although the chemistry of boron is still relatively young, it is developing at a pace where even specific areas of research are difficult to compile into a monograph. Besides the boron hydrides, boron-nitrogen compounds are among the most fascinating derivatives of boron. Nitrogen compounds exist in a wide variety of molecular structures and display many interesting properties. The combination of nitrogen and boron, however, has some unusual features that are hard to match in any other combination of elements. This situation was first recognized by Alfred Stock and it seems proper to pay tribute to his outstanding work in the area of boron chemistry. One should realize that about forty years ago, Stock and his coworkers had to develop completely new experimental techniques and that no guidance for the interpretation of their rather unusual data had been advanced by theoretical chemists. In this monograph an attempt has been made to explore the general characteristics of structure and the principles involved in the preparation and reactions of boron-nitrogen compounds. It was a somewhat difficult task to select that information which appears to be of the most interest to "inorganic and general chemistry" since the electronic relationship between a boron-nitrogen and a carbon-carbon grouping is reflected in the "organic" character of many of the reactions and compounds."
