Copyright 1967 by CRC Press, Inc. PREFACE The present volume is a revised and enlarged third edition of the book formerly titled TABLES FOR IDENTIFICATION OF ORGANIC COMPOUNDS, Four new classes of com- pounds, i.e., sulfonyl chlorides, sulfonamides, thiols and thioethers were added, bringing the number of classes included in the book to twenty-six. The tables of alkanes, alkenes, alkynes, aromatic hydrocarbons, phenols, nitriles and sulfonic acids were all thoroughly revised and considerably enlarged. In all, the addition of 2400 compounds to the third edition, raised the total number of parent compounds in the book to over 8150. Three tables containing the dissociation constants of more than 1050 phenols, organic acids and organic bases were added. Correlation charts for I.R., Far I.R. and N.M.R. were also included. Explanatory sections entitled "Explanations and References" precede the tables. In these sections the formulas of the derivatives and the full reaction equations for their preparation by the most important methods, together with some essential details and references to their preparations, are given. An index covering both the names and synonyms of the compounds was added at the end of the book. An index listing the names of all tables and major subjects was also added. The main objective of this book is to assist chemists in the identification of organic compounds. The organization of the compounds in classes according to increasing boiling points should also assist in the search for standard vapor phase chromatography work. For further information of techniques of organic analysis one or more of the following books should be consulted: N. D. Cheronis, J. B. Entrikin and E. M. Hodnett, Semimicro Qualitative Organic Analysis, 3rd Ed., Interscience Publishers, New York, 1965. L. Meites, Handbook of Analytical Chemistry, McGraw Hill Book Co., 1963. F. Feigl, Spot Tests in Organic Analysis, 6th Ed., Elsevier Publishing Co., 1960. A. I. Vogel, A Textbook of Practical Organic Chemistry, 3rd Ed., Longmans Green and Co., London, 1957. R. L. Shriner, R. C. Fuson and D. Y. Curtin, The Systematic Identification of Organic Compounds, 4th Ed., John Wiley and Sons, New York, 1956. F. Wild, Characterization of Organic Compounds, 2nd Ed., Cambridge University Press, 1958. The publication of the third edition would not have been possible without the work of those involved in the preparation of the earlier editions. The editor is thankful for the part in the earlier work contributed by Professors M. Frankel, S. Patai and A. Zilkha, and the late Mr. R. Farkas-Kadmon. Thanks are due also to Mrs. E. Shohamy and Mr. A. Glazer for assisting in collection of new data, to Mrs. Y. Elmaleh for typing the index, and especially to Prof. S. Patai, who as consulting editor, read all the new material and gave many helpful suggestions. The cooperation of Dr. Robert C. Weast and Mrs. F. Thomas in the publication of the book is gratefully acknowledged. z. R. Jerusalem January 196 7 Copyright 1967 by CRC Press, Inc.

EXPLANATIONS AND REFERENCES TO THE TABLES The following section gives explanations and references for the preparation of the derivatives appear- ing in the Tables Formulas of the derivatives as well as the mam methods for their preparation are given Usually, only the reagents and the solvents required for the preparation of a derivative are mentioned without specific details for the reaction conditions and the exact procedure The aim of these notes is mainly to enable the worker to choose the method preferable in the conditions and the reagents available to him in his labora- tory for the denvatization of his specific compound However, THIS IS ONLY A REFERENCE SECTION AND NOT AN INSTRUCTION MANUAL AND THE QUOTED REFERENCES SHOULD BE CON- SULTED FOR THE ACTUAL PREPARATION OF DERIVATIVES, ESPECIALLY REGARDING SAFETY HAZARDS INVOLVED IN THE WORK. References are usually given for the preparation of all the derivatives having separate columns in the Tables, as well as for important ones listed in the "miscellaneous" section of the Tables References to five different popular analytical textbooks are given, assuming that at least one of them, or another equivalent publication, would be available to the worker These are N D Cheroms, J B Entnkin and E M Hodnett, Semimicro Qualitative Organic Analysis, 3rd edition, Interscience, New York, 1965, quoted in the text as "Cheroms " R P Linstead and B C L Weedon, A Guide to Qualitative Organic Chemical Analysis, Butterworth Scien- tific Publication, London, 1956, quoted in the text as "Linstead " R L Shnner, R C Fuson and D Y Curtin, The Systematic Identification of Organic Compounds, 4th edition, John Wiley and Sons, New York, 1956, quoted in the text as "Shnner " A I Vogel, A Textbook of Practical Organic Chemistry, 3rd edition, Longmans, Green and Co , London, 1957, quoted in the text as "Vogel " F Wild, Characterization of Organic Compounds, 2nd edition, Cambridge University Press, Cambridge, 1958, quoted in the text as "Wild " In addition, leading references from the original literature are also given Although the literature cover- age is not complete (especially for the common derivatives) it was attempted to describe different methods, and to give as many references as possible to less common derivatives having limited scope More references can be found in the textbooks mentioned above Derivatives appear either in a separate column or in the "miscellaneous" section in the Tables, where separate columns are usually given for derivatives which should be tried first, and for which enough data are available Derivatives which should be tried as a second choice, or preferred derivatives for which not enough data are available appear in the "miscellaneous" section The explanations and the references for the different derivatives are arranged usually in the same order as in the Tables Occasionally, this order is changed in the explanatory notes in order to describe the derivatives in a logical order (eg, in Table 17 the phenylurethane appears in a separate column, while the phenylhydantom appears in the "miscellaneous" section in the "ex- planations and references" section the phenylhydantom appears directly after the phenylurethane) Derivatives which are followed by an asterisk are those recommended for first trial Other derivatives should be tried after these Although "Ar" usually stands for monovalent aromatic group, we used it a few times in the following sec- tions as a polyvalent aromatic residue This was done only for demonstration purposes Copyright 1967 by CRC Press, Inc.
