This volume C 1 is the first supplement volume to "Phosphor" C which was published in 1965 and covers the compounds of phosphorus. Starting with the binary species formed between phosphorus and hydrogen, the present volume deals with the neutral mononuclear compounds PH through PH ; the ions featuring the same stoichiometric composition are s covered in separate sections. PH and PH are the major initial gaseous decomposition products of PH and, thus, also 2 J intermediates in many of its gas-phase reactions. Both molecules and their ions have been thoroughly investigated by a variety of modern, high-resolution spectroscopic methods during the last three decades. The coverage of their physical, and mostly molecular, properties re presents the largest part of the first two chapters (PH and ions pp. 2 to 47; PH and ions pp. 47 2 to 111). PH is the only compound described in this volume which is thermally stable under normal J conditions. It is the phosphorus analog of ammonia, but exhibits, however, a quite different chemical behavior towards most elements and compounds. The majority of its physical, and in particular spectroscopic, properties have been determined in great detail since the sixties, partially in regard to spectroscopic investigations of the atmospheres of the outer planets.

This fourth volume of the Supplement Series supplying the Main Volumes of the series "Perfluorohalogenoorgano Compounds of Main Group Elements" (Part 1 to 9) covers the heterocyclic compounds of nitrogen as the last main group element of this series. Compounds of the elements of main group 1 to 4, 6 (without 0), and of P, As, Sb, Bi, and I are presented in the Supplement Volumes 1 to 3. Concept, organization, and selection as to coverage of the material are the same as in the preceeding volumes. Title compounds are either newly synthesized ones or those compounds already referred in the Main Volume Parts 5 and 6 for which new facts have been published. I wish to thank Prof. Dr. Dr. h. c. E. Fluck and his co-workers for their excellent cooperation and many colleagues for providing reprints and patents. One of us (U. Niemann) thanks Philips GmbH Forschungslaboratorium Aachen for generous support. November 1987 Bochum, A.

The volume describes the chemical and physical properties of the approximately 80 known bromine compounds and ions which contain oxygen and/or nitrogen, and which may include hydrogen as well. The class of bromine-oxygen and bromine-oxygen-hydrogen compounds comprises several well-known species. Their description accounts for approximately three-quarters of the volume. The BrO radical and the BrO3 ion are the most and best studied among all binary bromine-oxygen species. BrO was recently recognized to play a role in some reaction sequences depleting the ozone concentration in the stratosphere. Bromate-ion-driven chemical oscillator systems have attracted much interest in recent decades. Thus data on single reaction steps which involve BrO3, BrO2, and the oxoacides of bromine - HBrO, HBrO2, and HBrO3 - are reviewed in detail; a comprehensive description of the oscillating systems, however, is beyond the scope of this volume. The remaining one-quarter of the volume is devoted to bromine-nitrogen and bromine-nitrogen-oxygen compounds. Bromine azide and nitrosyl bromide are the most comprehensively studied of these, accounting for almost half of this section.
