Available in PDF, EPUB and Kindle. Book excerpt: The volume presents compounds of boron with nitrogen and with fluorine and updates the preceding supplement series. The majority of the boron-nitrogen compounds includes amine-boranes (more than 250 compounds), pyrazaboles, and nitrogen-substituted boron cations. Emphasis is placed also on ammonium borates and on three- and four-coordinate boron-nitrogen compounds containing B-O bonds. In the fluorine part, special attention was given to BF3 and to the tetrafluoroborates. As many as 500 recent publications on applications of BF3 and its etherate have been evaluated. Ions, radicals, and neutral compounds containing only B, F, and partly also H or O are discussed. Moreover, linear and cyclic organylfluoroboranes and aminofluoroboranes and their adducts are treated. Peroxy species are found among the OxBFy-group compounds with four-coordinate boron.

Available in PDF, EPUB and Kindle. Book excerpt: This volume, part 3 of the third supplement, continues the updating of the previous volumes on boron compounds: "Boron Compounds" Vols. 1 - 20, "Boron" 1st Suppl. Vol. 1 - 3 (1980/81), "Boron" 2nd Suppl. vols. 1 + 2 (1980/83). This volume deals with the compounds of boron with nitrogen and of boron with fluorine. The modifications of boron nitride are now important materials in modern technology. They have many applications, e.g. as fibers or coatings, in ceramics or alloys, as fillers in organic polymers, for machining of metals and as solid lubricants. They are used in the preparation of semiconductors and in laser nuclear technology. In the chapter on L-triorganyl-N-triorganylborazines, (-Br-Nr-)3, the compound (-B(i-C3H7)-N(t-C4H9)-)3 is the first species having a Dewar-borazine structure, which contains a 1,4 bond and two parallel double bonds in the 6-ring system. Trifluoroborane, BF3, and also its adduct with ether, is important especially in catalytic applications. Among tetra-fluoroborates ÄNOÜ ÄBF4Ü, ÄNO2Ü ÄBF4Ü and ÄNF4Ü ÄBF4Ü are also described. The systems with C1, Br and J with chalcogenes, and finally the carboranes, are contained in the final 4th volume of this series. Volume 4 will also include a formula index for volumes 1 to 4.

Available in PDF, EPUB and Kindle. Book excerpt: 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 techniq'\les and that no guidance for the interpreta tion 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-nitroge~ 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.

Available in PDF, EPUB and Kindle. Book excerpt: The present issue, Volume 3a of "Boron Compounds" 4th Supplement of the Gmelin Hand book, presents the description of boron nitride and a part of other boron compounds containing nitrogen. Volume 3 b (to be published Later) will complete the presentation of the boron-nitrogen compounds and will also cover boron compounds containing fluorine. Due to technical circumstances, Volume 1 (systems with hydrogen) and Volume 2 (systems with oxygen) of this particular supplement will be published subsequently, whereas Volume 4 (boron compounds containing CL, Br, I, S, Se, and Te, as well as a section containing carboranes) has already been published. ALL volumes of the 4th Supplement will be augmented by a formula index. The IUPAC nomenclature is generally adhered to; occasional abbreviations for compounds are explained in the text. A positive sign for the chemical shifts of the NMR signals indicates a 1 13 downfield shift from the references, usually internal (CH ) Si for 6 H and 6 C and external 3 4 11 (C H h0-BF for 6 B, others being specified. 2 5 3 In contrast to more recent publications but remaining consistent with the previous volumes of the Boron Series, the iminoborane structure is written as B=N and not as B=N. In fact, the real electronic structure is more realistically symbolized by B=N, but it seems reasonable to avoid =NR in accordance with the commonly accepted "iminoborane" nomenclature.

Available in PDF, EPUB and Kindle. Book excerpt: The present issue, Volume 2 of "Boron Compounds" 4th Supplement of the Gmelin Hand book, updates the previous issues by reporting the literature on boron-oxygen systems published up to 1988. For some important recent developments literature is covered through mid-1992; this concerns, for example, the compounds ~-Ba3[B306h and U[B305J which became of interest as materials with nonlinear optical properties. The volume directly com plements the earlier "Boron Compounds" 3rd Supplement Volume 2. In the original literature, alternative formulations are frequently used for the same com pound. This is especially true for many borates. Often, these species are neither completely heteropolar nor covalent, and an experimentally based decision has not been made. Hence, the use of brackets does not necessarily reflect a truly salt-like character. Volume 1 (systems with hydrogen and noble gases) of this particular supplement will be published subsequently, whereas Volume 3a (boron and nitrogen), Volume 3b (boron and nitrogen, boron and fluorine), and Volume 4 (boron compounds containing Cl, Br, I, S, Se, and Te, as well as a section containing carboranes) have already been published. All volumes of the 4th supplement will be augmented by a formula index. The IUPAC nomenclature is generally adhered to; thf means tetrahydrofuran; and occa sionally additional abbreviations for compounds are explained in the text. Positive signs for chemical shifts of the NMR signals indicates downfield shifts from the references, usually internal (CH3)4Si for olH and 013C with others being specified.

Book excerpt: The 3rd supplement continues the updating of the original 20 volumes on boron com pounds published between 1974 and 1979. The first supplement to this series brought the literature closing date uniformly to the end of 1977, whereas the two volumes of the 2nd supplement have extended the literature coverage of boron compounds to 1980. Selection and presentation of data parallel the style selected for the two previous supplement volumes, which appeared in 1980/1 and 1982/3, respectively. The Gmelin Principle of the Last Position is largely adhered to, excepting substituted polyboron species containing boron-boron bonds (all of which are found in Chapter 2 within the system boron-hydrogen). Examples of organic derivatives are included, especially in those cases where the carbon-free species are not known; and the carboranes are treated comprehensively. The literature is considered through 1984. Part 1 of the present 3rd supplement contains the systems boron-noble gases and boron hydrogen; Part 2 contains the system boron-oxygen. Part 3 will contain the systems boron nitrogen, boron-fluorine, and boron-chlorine; the remaining systems and a formula indexwill be included in the final 4th part of this supplement. The first chapter of the present volume on the compounds of boron and oxygen provides sections on the binary boron oxides, including some radicals, and the anhydrous berate ions. The following chapter describes boron-oxygen compounds with hydrogen or organyl groups.
