An attempt is made to group syntheses in different chapters in accordance with specific areas of interest. For example, the first chapter presents the syntheses of some metal nitrosyls and the last chapter is devoted to the preparation of a few compounds of biological interest. There is also a chapter on the syntheses of ligands, which might be more appropriate for a volume of Organic Syntheses. My justification for including this chapter is that the compounds are often prepared by inorganic chemists and the ligands are certainly largely used by coordination and/or organometallic chemists. Other syntheses are grouped in different chapters with more traditional headings. Inorganic Syntheses, Inc., is a nonprofit organization dedicated to the selection and presentation of tested procedures for the synthesis of compounds of more than routine interest. The Editorial Board seeks the cooperation and help of the entire scientific community in its attempt to realize these goals. Persons familiar with the syntheses of important compounds should take the initiative to prepare manuscripts suitable for INORGANIC SYNTHESES and to encourage others in the field to do likewise. Equally important are the persons willing to devote the time to check these procedures and to work out with the submitter any significant alterations that may improve the synthesis. My experience in working with submitters and checkers has been most gratifying, and I am pleased to acknowledge their cooperation and help in preparing Volume XVI. Directions for submitting syntheses for INORGANIC SYNTHESES follow this Preface. The editor for Volume XVII is A. G. MacDiarmid, for Volume XVIII is B. E. Douglas, and for Volume XIX is D. F. Shriver. Finally I thank those members of Inorganic Syntheses, Inc.. who read the original manuscripts and gave me valuable advice and help. I am espe- cially thankful to Professors Robert D. Feltham and Devon W. Meek for contacting prospective authors for syntheses of metal nitrosyls and of ligands, respectively. I also thank S. Kirschner and W. H. Powell for their help. Fred Basolo ix NOTICE TO CONTRIBUTORS The INORGANIC SYNTHESES series is published to provide all users of inorganic substances with detailed and foolproof procedures for the preparation of important and timely compounds. Thus the series is the concern of the entire scientific community. The Editorial Board hopes that all chemists will share in the responsibility of producing INORGANIC SYNTHESES by offering their advice and assistance in both the formu- lation of and the laboratory evaluation of outstanding syntheses. Help of this kind will be invaluable in achieving excellence and pertinence to current scientific interests. There is no rigid definition of what constitutes a suitable synthesis. The major criterion by which syntheses are judged is the potential value to the scientific community. An ideal synthesis is one which presents a new or revised experimental procedure applicable to a variety of related compounds, at least one of which is critically important in current re- search. However, syntheses of individual compounds that are of interest or importance are also acceptable. The Editorial Board lists the following criteria of content for submitted manuscripts. Style should conform with that of previous volumes of IN- ORGANIC SYNTHESES. The Introduction should include a concise and critical summary of the available procedures for synthesis of the product in question. It should also include an estimate of the time required for the synthesis, an indication of the importance and utility of the product, and an admonition if any potential hazards are associated with the pro- cedure. The Procedure should present detailed and unambiguous labora- tory directions and be written so that it anticipates possible mistakes and misunderstandings on the part of the person who attempts to duplicate the procedure. Any unusual equipment or procedure should be clearly described. Line drawings should be included when they can be helpful. All safety measures should be stated clearly. Sources -of unusual starting materials must be given, and, if possible, minimal standards of purity of reagents and solvents should be stated. The scale should be reasonable for normal laboratory operation, and any problems involved in scaling the procedure either up or down should be discussed. The criteria for judging the purity of the final product should be delineated clearly. The xi
