THE BEILSTEIN INFORMATION-SYSTEM IS NOT A REACTION DATABASE, OR IS IT

The Beilstein Information System is the world's largest collection of chemical properties of organic compounds. The Beilstein database conta ins over 5 million compounds with associated properties, covering the literature period from 1779 to 1991. The gap to the present literature will be closed in 1994. The properties covered most thoroughly within the Beilstein Information System are physical data and chemical behav ior. Chemical behavior data contain preparations and reactions of almo st all compounds in the database. For many compounds more than one pre paration or reaction is contained in the database. Thus more than 8.7 million preparations and reactions are described. On-line access to th ese preparations and reactions is still limited. This paper describes the current access and future plans for the development of a full Beil stein Reaction Database.
