Organic chemistry research has moved rapidly toward synthesis and medicinal application of nitrogen-containing compounds such as triazenes, triazines, and hydroxytriazenes due to their excellent biological activities. Many of them are presently in clinical trials. Triazene compounds have excellent medicinal properties and limited toxicity. Hydroxytriazenes are excellent chelating agents for transition metals. Newer studies show very promising biological and medicinal applications of these classes of compounds. Hydroxytriazenes and Triazenes: The Versatile Framework, Synthesis, and Medicinal Applications highlights synthetic methods, recent advances, and potential applications of triazines, triazenes, and hydroxytriazenes. This book includes holistic information on synthetic methods for novel compounds based on this moiety, up-to-date information on the how and why of their diverse or even multitargeted medicinal application, and future state of the art of both aspects. Other features include: Highlights recent advances and diverse possible applications of biological functions Covers the chemistry of triazine, triazene, and hydroxytriazene systems On the basis of in silico predictions, the book highlights synthetic methods and their applications A valuable source of information for those actively engaged in medicinal chemistry, drug discovery, and synthetic organic chemistry

The present volume, "Manganese" D 5, continues the description of the manganese complexes. The arrangement of the complexes in these D volumes is based on the ligand type. The introduction, on p. 1, shows the classes of complexes, which have already been described in Chapters 1 to 21 in the Volumes D 1 (1979), D 2 (1980), D 3 (1982), and D 4 (1985). In Chapters 22 to 29 of this volume are treated complexes with amine-N-polycarboxylic acids, hydrazinecarboxylic acids, amides, hydrazides, derivatives of hydroxylamine (e.g., hydroxamic acids), oximes and nitroso compounds, azo compounds, and triazenes. A survey at the beginning of each of these sections gives information on the most characteristic features of the various complex types. Because of the complexometric relevance of the complexes with amine-N-polycarboxylic acids, there are many studies concerning the existence and the stability of the complexes in solution. Numerous X-ray investigations, reported for the complexes with urea or with amides and hydrazides of carboxylic acids, show the different structures of the compounds as a result of the varying bonding sites of the ligands. Complexes with hydrazides (e.g., with isonicotino hydrazide) are of special interest, due to their biological activity. Complexes with hydroxamic acids, oximes or azo compounds have been studied mostly in aqueous organic or pure organic solvents. The characteristic intense colors of many solutions are used for the analytical determination of manganese.

'Bretherick' is widely accepted as the reference work on reactive chemical hazards and is essential for all those working with chemicals. It attempts to include every chemical for which documented information on reactive hazards has been found. The text covers over 5000 elements and compounds and as many again of secondary entries involving two or more compounds. One of its most valuable features is the extensive cross referencing throughout both sections which links similar compounds or incidents not obviously related. The fifth edition has been completely updated and revised by the new Editor and contains documented information on hazards and appropriate references up to 1994, although the text still follows the format of previous editions. Volume 1 is devoted to specific information on the stability of the listed compounds, or the reactivity of mixtures of two or more of them under various circumstances. Each compound is identified by an UPAC-based name, the CAS registry number, its empirical formula and structure. Each description of an incident or violent reaction gives reference to the original literature. Each chemical is classified on the basis of similarities in structure or reactivity, and these groups are listed alphabetically in Volume 2. The group entries contain a complete listing of all the compounds in Volume 1 assigned to that group to assist cross referral to similar compounds. Volume 2 also contains hazard topic entries arranged alphabetically, some with lists. Appendices include a fire related data table for higher risk chemicals, indexes of registry numbers and chemical names as well as reference abbreviations and a glossary.
