Beilstein Handbook

The Beilstein database [20] has more than 8.3 million (October, 2002) organic substance records from the Beilstein Handbook and abstracted from about 180 journals in organic chemistry from 1779 to the present. AH documents are critically evaluated and peer-reviewed.

Beilstein File. Beilstein first went on-line on STN International in December 1988 with information on 350,000 compounds, and several months later it was also on Dialog. Beilstein Online now comprises data on five million compounds. The organic substance records contain the critically reviewed and evaluated documents from the beilstein Handbook of Organic Chemist main volume and supplements 1—5, which cover the chemical Hterature from 1779 through 1979. These evaluated data are indicated as Handbook Data in the notes of Hterature references. The Beilstein Eile also contains organic substance records for unreviewed excerpts from the primary Hterature from 1980 to 1991. 

Beilstein Handbook of Organic Chemistry. This reference (55) is one of the most significant collections of data in organic chemistry. The physical and chemical properties of organic compounds are tabulated in more than 500 fields. Most of these fields are searchable, and a sample of the record for chlorobenzene [108-90-7] is shown in Table 3.

Fluoran compounds developing colors are not new, having been well known since early times. For example, the Beilstein Handbook of Organic Chemistry, XIX describes many fluoran compounds developing colors from yellow to red. These include 3, 6 -dimethoxyfluoran (4 yellow), 3 -chloro-6 -diethylaminofluoran (5 vermilion), and 9 -diethylaminobenzo[a]fluoran (6 red). 

Beilstein. Beilstein [63], a structure and factual database covering organic chemistry, contains more than 7,688,485 substance records (3/2000). The organic substance records contain reviewed and evaluated documents from the Beilstein Handbook of Organic Chemistry as well as data from 120 journals in organic chemistry covering the period 1779 to the present. Beilstein Database is commercially available in several electronic formats.

Numeric. Researchers routinely use reported nunierie measurements and data in their work. Numeric databases include the Beilstein Handbook of Organic Chemistry, ihc Gmelin Handbook of Inorganic and Orgunomelallic Chemistry, properly daia networks the Materials Property Data Network Inc.

Interestingly, the Beilstein Handbook (Ref. 10) used this type of labelling in the III-IV supplement, while, for supplement V, a change to sugar terms is evident. Originally, the trivial names isosorbide, isomannide, and isoidide were used in the main volume, as well as in Supplements I and II. It should, however, be pointed out that Beilstein names in supplement III-IV are based on an older stereochemical reference system according to which 3 is (3aR)-(3ar, 6ac)-hexahydrofuro-[3,2-h]furan-3c, 6f-diol. 

The Beilstein Handbook of Organic Chemistry (Beilstein s Handbook der Organi-schen Chemie) is a reference work containing information and data relating to the structure, preparation and properties of organic compounds reported in the primary literature. The information is condensed into short entries, each of... 

For those users of the Beilstein Handbook who are unfamiliar with the German language, a pocket-size Beilstein Dictionary (German/English) has been compiled by the Beilstein editorial staff and is also available free of charge. The contents of this dictionary are also to be found on the green pages in either of the subvolumes E III/IV 22/7 or E IV 6/4. 

The best way of finding the entry for a particular compound in the Beilstein Handbook is to identify in which volume the compound is listed, and then to consult the appropriate volume index. In order to identify the volume of interest a few basic principles of the Beilstein System need to be understood and these are described below.

What a beautiful tool is cyanuric chloride for the chemist working in chemical synthesis Three chlorine atoms offer reaction with a large proportion of the chemicals listed in the Beilstein Handbook or the Chemical Abstracts Index. Not only that the chlorine atoms are reasonable enough not to react simultaneously but, under adequate conditions, stepwise, allowing myriads of potential combinations. Furthermore cyanuric chloride has been and is a relatively cheap key material it can be produced quite easily from such basic materials as chlorine and hydrocyanic acid. 

Beilstein uses a number of additional stereochemical descriptors for specialised situations. Examples are (RS), R, S, and H. For full details, see the booklet Stereochemical Conventions in the Beilstein Handbook of Organic Chemistry, issued by the Beilstein Institute, and Section 7.6.
