摘要:

AbstractIn this brief review, it is attempted to point up the importance of chemical equilibria in structural inorganic chemistry and to show how the kind and yield of various molecules may be treated quantitatively. Because of the importance of kinetic control in organic chemistry and because the chemistry of carbon compounds is by far the most advanced branch of general and descriptive chemistry, preparative inorganic chemists have often overemphasized the value of reaction‐mechanism theory to their studies and have thereby neglected the powerful quantitative approach of thermodynamics which may be used in equilibrated systems. The general theorems for treating in terms of small molecular segments the multitude of equilibria present in families of compounds are surveyed superficially with the hope that the interested reader will turn to the original papers for details. Not only physical‐inorganic chemists, but also those interested solely in preparative work can advantageously employ the theoretical ideas discus

AbstractSome years ago, WittigG. Wittig, Angew.Chem.70, 65 (1958).pointed out that ate‐complexes are characterized by anionic activation of the substituents attached to the central atom. The behavior of these compounds thus contrasts with that of the onium‐complexesCf.E. Müller: Neuere Anschauungen der organischen Chemie.

These two types of complexes form together two complementary aspects of organic coordination chemistryMetal‐carbon π‐complexes are excluded from the following

摘要:

Abstractα‐Carbonyl azo compounds such as diesters of azodicarboxylic acids, diacylazo compounds, and esters of arylazocarboxylic acids are highly reactive. They add e.g. to amines, aromatic compounds, olefins, CH acids, Grignard and diazo compounds, aldehydes, ketones, and ketenes. These reactions can be used for the preparation of triazanes, hydrazones, oxa‐diazoline, azomethinimine, and diazetidine derivatives, etc. α,α′‐Dicarbonyl azo compounds are among the strongest dienoph

摘要:

AbstractThe topological analysis of chiral molecular models has provided the framework of a general system for the specification of their chirality. The application, made in and before 1956, of this system to organic‐chemical configurations is generally retained, but is redefined with respect to certain types of structure, largely in the light of experience gained since 1956 in the Beilstein Institute and elsewhere. The system is now extended to deal, on the one hand, with organic‐chemical conformations, and, on the other, with inorganic‐chemical configurations to ligancy six. Matters arising in connexion with the transference of chiral specifications from model to name are considered, notably that of the symbiosis in nomenclature of expressions of the general system and of systems of confined scope.For corrigendum see DOI:10.1002/anie.196
