Contains the procedures previously published in annual volumes 50-59, revised and updated where necessary. Efforts have been made to standardize the style of experimental procedures and the presentation of spectroscopic data. Increasing emphasis on the toxicology of organic compounds has led to the inclusion of additional hazard warnings, particularly for benzene, hexamethylphosphoric triamide (HMPA), and methyl iodide at the many places where they appear. Some experimental procedures have been improved, references have been added, and the index has been greatly expanded and simultaneously consolidated for efficient and easy use.
