Book Description
A very large number of organo derivatives is formed by the Group IV ele ments silicon, germanium, tin, and lead. In comparing the general properties of these elements, Table 1. 1 shows that the first ionization energies decrease (though not in a regular way) with increase in size and atomic number, con sistent with the general increase in metallic character of the elements. Electro negativity values (which have been the subject of considerable controversy) show no clear trend. Although purely inorganic compounds of tin(n) and leaden) are well known, almost all organo Group IV derivatives show an oxidation state of IV. Bonds to carbon become weaker on passing from silicon to lead, as do the element-element bonds themselves. With any particular element M (M = Si, Ge, Sn, or Pb), there is a small decrease in bond energy in the order: M-Ph > M - Me > M - Et. Although accurate data for organo derivatives are lacking, strengths of bonds to other elements probably decrease in the order: M-F> M-O > M-CI > M-H ~ M-N ~ M-S ~ M-Br > M-I, while for a particular element X, the order is: Si-X > Ge-X > Sn-X > Pb-X. It is therefore understandable that reactions leading to Si-F, Si-O, or Si-CI bonds are especially favoured in a thermodynamic sense.

Book Description
This volume is exclusively devoted to tetramethyllead. Owing to the recent large-scale use as an antiknock agent, its application, toxicological, biological, and environmental aspects are given much attention besides its chemical and physical properties. - Literature coverage up to 1986.

Book Description
The present volume opens the Gmelin series on organogermanium compounds, that is, those compounds containing at least one germanium-to-carbon bond. This whole series is being coordinated by Professor J. Satge of the Universite Paul Sabatier in Toulouse. Germanium is of historical interest because its existence was predicted by Newlands in 1864 and by Mendeleeff in 1871 although it was not isolated until1887 by Winkler. Mendeleeff's predictions of the properties of germanium and its compounds by comparison with what was known of the chemistry of its neighbors, silicon and tin, proved remarkably accurate and included predictions of the existence of organic derivatives GeR and of their properties. 4 Although significant applications are as yet lacking for organogermanium compounds in contrast to organo-silicon, -tin, and -lead compounds there has been considerable interest in the parallel development of its chemistry. Up to 1983 about 1500 publications have appeared on organogermanium chemistry. The material of the present series will be grouped in a similar way as for the organotin series beginning with compounds containing only one germanium atom (mononuclear com pounds) and continuing with binuclear up to polynuclear compounds. Within each group the compounds are arranged by the kind of non-carbon substituents rather than by following the usual Gmelin principle of the last position using the Gmelin system of elements.

Book Description
The Book Is A Revised Edition Of A Lucid And Stimulating Introductory Account Of Organometallic Chemistry, An Exciting And Rapidly Developing Interdisciplinary Branch Of Science.A Characteristic Feature Of This Book Is The Presentation Of An Integrated (Covering Different Facets Usually Dealt With Either In Organic Or/And Inorganic Texts) View Of The Rapidly Developing Field Of Organometallic Chemistry. Attempts Have Been Made To Choose The Latest Examples To Illustrate The Fundamental Properties As Well As The Synthetic Procedures Of Organometallic Chemistry. Other Features Include: (A) An Interesting Brief Historical Background Of The Subject Including Some Quotations From Relevant Nobel Lecture Accounts Of Epoch Making Advances By The Discoverers Themselves, (B) The Adoption As Far As Possible Of The Iupac Rules Of Nomenclature, (C) A Brief Account Of The Rapidly Emerging Organometallic Chemistry Of The F-Elements, And (D) Inclusion Of Study Questions At The End Of Each Chapter.During The Revision Of The Book, The Latest Examples Have Replaced The Older Ones Wherever Feasible. The Book Would Be Extremely Useful As A Basic Text For B.Sc. (Hons.) And M.Sc. Chemistry Students.

Book Description
At long last: The second, completely revised edition of this comprehensive standard reference. Alwyn G. Davies has updated the contents of his book to reflect the current state of research into organotin chemistry. He covers all aspects in detail, such as its synthesis, characterization, structures and applications, while also devoting space to such hot topics as environmental issues. This new edition also includes a CD-ROM with more than 5,000 references, making this database an invaluable tool for everyone working in the field. "The text is well written, extremely accessible and very comprehensive: particularly impressive is the inclusion of up-to-the-minute references in these areas...." - Advanced Materials, 13 (1998) "The standard of production is very good, with well-structured tables and an abundance of clear formula schemas, which enable the reader to quickly grasp the essence of the text." - Angewandte Chemie 16, 1997
