Since 1921, Organic Syntheses has provided the chemistry community with detailed,reliable, and carefully checked procedures for the synthesis of organic compounds.Some procedures describe practical methods for the preparation of specific compoundsof interest, while other procedures illustrate important synthetic methods with generalutility. Each procedure is written in considerably more detail as compared to typicalexperimental procedures in other journals, and each reaction with its characterization datahas been repeated several times and carefully checked for reproducibility in the laboratory of a member of the Board of Editors.
