Download or read book B Boron Compounds written by Gert Heller and published by Springer. This book was released on 2014-03-12 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 3rd supplement continues the updating of the original 20 volumes on boron compounds published between 1974 and 1979. The first supplement consisting of 3 volumes covered all the literature uniformly up to the end of 1977, whereas the two volumes of the 2nd supplement have extended the literature coverage of boron compounds to 1980 and the four volumes of the 3rd supplement to 1984. The present volume continues the description of boron compounds with halogens, presenting those with chlorine, bromine and iodine. The compounds with chalcogens are completed here along with those of boron with S, Se, Te and Po. The final chapter on carboranes contains the carboranes themselves, together with metallacarboranes, and in the last section a description of carborane-containing polymers, mostly derived from the three isomeric dicarbadodecarboranes. Volume 4 of the 3rd supplement brings this supplement series to an end. It will be supplemented by a separately appearing index volume, which contains all the boron compounds dealt with in volumes 1 - 4 of this supplement series.
Download or read book Boron and Cl Br I S Se Te Carbonares written by Gert Heller and published by Springer. This book was released on 1991-11-04 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume encompasses the compounds of boron with Cl, Br, I, S, Se, and Te. The large final chapter treats carboranes and metallocarboranes and gives a listing of carborane-containing polymers. Each chapter continues the corresponding chapter of the preceding supplement series, thus keeping information of the desired topics current. Among the wealth of boron compounds two of these may be especially mentioned: BCl3 and carboranes containing five boron atoms. Boron trichloride has become an important chemical agent, and much is known of its preparation, purification, and application. BCl3 is a preferred boron-supplying compound in chemical vapor deposition to prepare boron carbide or boron nitride. BC13 is also frequently used in dry-etching, boriding, and doping processes, and as a polymerization catalyst. Recent interest in the field of C2B5H7 carboranes and their derivatives stems from detailed investigations on a large number of isomerisation reactions and their mechanisms.

Download or read book Boron and Oxygen written by Gert Heller and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 313 pages. 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.

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.
Download or read book Index Formula Index written by Helga Hartwig and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gmelin Formula Index and its First Supplement covered those volumes of the Eighth Edition of the Gmelin Handbook which had been issued up to the end of 1979. The present Second Supplement updates the Index by inclusion of the volumes which appeared up to the end of 1987. With this Second Supplement all compounds described in the Gmelin Handbook of Inorganic Chemistry in the period between 1924 and 1987 can be located. The basic structure of the Formula Index remains the same as in the previous editions. Computer techniques were employed in the preparation and print of the Second Supple ment. The data acquisition, sorting, and further data handling were performed with the aid of aseries of computer programs developed by staft members of the former "Online Group" of the Gmelin Institute, now at Chemplex GmbH, and by the printer" Universitäts druckerei H. Stürtz AG, Würzburg ". Whereas the Handbook itself will continue to appear in printed form, the present Second Supplement of the Index is intended to be the last one issued in print. The cumulated contents of the Index and its Supplements are contained in the Gmelin Formula Index (GFI) database which is available to the scientific community via STN. This database will be updated annually to include the published Handbook volumes.
