Chapter 16: ChemRXN<br />

What Is It<br />

ChemRXN is a class of databases of chemical<br />

reactions which include literature citations,<br />

products, reactants, solvent and catalyst data, yields,<br />

and reaction conditions. ChemRXN consists of<br />

ChemPrep and ChemSelect.<br />

How Is It Useful<br />

ChemRXN provides ready access to information<br />

useful in planning a chemical synthesis. A reaction<br />

query can search for all reactions that:<br />

• Yield a particular product<br />

• Use a particular catalyst or solvent<br />

• Consume a particular reactant<br />

• Have been published by a certain author<br />

For example, you can search for reactions which<br />

produce benzofurans in greater than 90% yield.<br />

ChemPrep<br />

ChemPrep is a carefully prepared chemical reaction<br />

database from the Institute for Scientific<br />

Information (ISI). ISI is one of the largest and most<br />

reputable providers of scientific information, and<br />

has a number of scientific databases available<br />

including exhaustive reaction and molecular<br />

literature databases.<br />

Directory: ChemPrep<br />

Filenames: Chemprep.cfw, Catalyst.cfw,<br />

Reaction.cfw, Solvent.cfw<br />

Number of Reactions: 16,761<br />

Key Fields:<br />

• Structure (reaction)<br />

• Reaction Formula<br />

• Abstract<br />

• Molecular Weight (components)<br />

• Atmosphere<br />

• Reaction text<br />

• Time<br />

• Key phrases<br />

• Pressure<br />

• Reflux<br />

ChemPrep has a principal form or main screen,<br />

Chemprep.cfw, and three associated forms:<br />

• Reaction.cfw<br />

• Solvent.cfw<br />

• Catalyst.cfw<br />

Reaction.cfw shows the reaction diagram in a larger<br />

window. It is useful in case the reaction is<br />

complicated or has large molecules or many<br />

components. Reaction.cfw is called from the main<br />

screen by clicking the zoom Reaction button. The<br />

“view Solvents” and “view Catalysts” buttons<br />

provide larger views of the solvent (form<br />

Solvent.cfw) and catalyst (form Catalyst.cfw)<br />

molecules which appear in the scrolling lists on the<br />

right of the main screen. Each of these associated<br />

forms has a button to return to the main screen.<br />
