摘要:

AbstractChemistry judging by its applications, physics according to its methods, and heavily reliant upon the tools of mathematics—that is what makes theoretical chemistry. And yet that is where its strength lies—in the variety of these sciences. It is quite natural that, in answer to specific problems, results and methods can sometimes be developed whose scope extends far beyond the original application. Rather it is a mark of quality if consequences can be found in chemistry and physics and the pathway leadsvianew mathematical procedures and concepts. Regrettably, any publication aiming to present such aspects will usually encounter little resonance since the linguistic confusion in science, its disciplines, and subdisciplines, lies like a veil over our understanding. The author nevertheless wishes to attempt to present, in a series of articles, results of research into chemical themes in a manner designed to appeal to the interest of chemists, without neglecting interdisciplinary aspects. All that is required to understand the argumentation is a lively interest.The first two articles are concerned with the chirality of molecules, and in particular with questions relating to the chirality phenomenon of molecules in the framework of molecular classes. In view of the algebraic nature of the mathematical methods adopted, it is not surprising that precise statements result. It appears of primary interest to establish the degree to which such statements can be considered valid for molecular models or molecules themsel

摘要:

AbstractReactions of transition metal complexes in which an organic ligand undergoes intramolecular metalation with formation of a metal‐carbon σ bond are termed cyclometalation reactions. This article provides a general summary of our knowledge of these reactions, and discusses them in terms of their scope, mechanisms, and utility in organic synthesis, particularly of heterocyclic molecul

摘要:

AbstractFormulation of the Schrödinger equation (1926) laid the foundation for a theory of the electronic structure of molecules, and thus for a physically sound theory of the homopolar chemical bond. Physicists reached a qualitative understanding of the bond in diatomic molecules during the ensuing years 1927 to 1929, and of stereochemistry by 1931

摘要:

AbstractAdsorbed particles can be bound chemically to the surface of a solid (chemisorption). Modern variants of electron diffraction and electron spectroscopy now enable us to gain an insight into the nature of such surface chemical bonds, which play a key role in heterogenous catalysis and many other technically important phenomena such as adhesion, lubrication etc. Predominantly localized surface bonds can be compared to the covalent bonds in cluster compounds.
