ChemReact41 with InfoChem CD-ROM is a chemical reaction search system consisting of a database of about 41 000 high-yielding organic reaction types from key journals, search software, and the InfoChem CD-ROM for display of the complete InfoChem Reaction Database with 2.5 million reactions. Additional examples can be displayed offline from the InfoChem CD-ROM containing the complete set of 2.5 million reactions. Each different reaction type is represented only once and by one example but with reference to the total number of published examples. These reaction types have been selected by grouping all reactions with identical reaction centers and identical environments under one type. ChemReact is a subset of this large database with currently 370 000 reaction types out of the full data set. From this structural database, a reaction database of 2.5 million reaction was developed. This database encompasses information on 3.3 million organic and organometallic compounds published in the worldwide literature between 19. The original source of ChemReact is the VINITI/ZIC structural database which was developed jointly by the AllUnion Institute of Scientific and Technical Information of the Academy of Sciences of the USSR (VINITI) in Moscow and the German Zentrale Informationsverarbeitung Chemie (ZIC) in Berlin. The databases include ChemReact, a file of 370 000 organic reactions, and LiqCryst, a file of data on some 60 000 liquid-crystalline compounds. 1997, 37, 154-155Ĭhemical Databases from Springer Verlag Gertraud Griepke Springer Verlag, Tiergartenstrasse 17, D-69121 Heidelberg, Germany Received October 23, 1996XĬhemical databases offered by Springer Verlag are described.
