- Company Profile:
CambridgeSoft, based in Cambridge, Massachusetts, USA, is a cheminformatics software and consulting company. The company was founded in 1986 by Stewart Rubenstein, then a graduate student in chemistry at Harvard University, and has since remained independent. The company's historical main product ...
A stepwise reaction is a chemical reaction with at least one reaction intermediate and involving at least two consecutive elementary reactions.
Industry:Software
An opposing reaction is a chemical reaction for which the rate of change in a reactant or product involves constants of two "opposed" chemical reactions.
Industry:Software
A parallel reaction is a chemical reaction for which the expression for the rate of disappearance of a reactant is governed by the rate constants relating to several simultaneous reactions to form different respective products from a single set of reactions.
Industry:Software
An homolysis is the cleavage (or fission or dissociation) of a bond so that each of the molecular fragments between which the bond is broken retains one of the bonding electrons. A unimolecular reaction involving homolysis of a bond (not forming a cyclic structure) in a molecular entity containing an even number of (paired) electrons results in the formation of two radicals.
Industry:Software
A beta scission reaction is a chemical reaction where the main feature is the scission of a bond beta (connected to an adjacent atom) to the atom bearing a radical. A unimolecular reaction involving beta scission of a bond in a molecular entity results in the formation of a radical as one product with concomitant formation of an unsaturation in the other product.
Industry:Software
An elimination is a reaction where the main feature is elimination of two ligands (atoms or groups). In a 1,2-Elimination, the ligands are lost from adjacent centers with concomitant formation of an unsaturation in the molecule. In a 1,n-Elimination (n>2), the ligands are lost from non-adjacent centers which may result in formation of a new ring. In a 1,1-Elimination, the resulting product is a carbene or "carbene analogue."
Industry:Software
A molecular rearrangement is traditionally any reaction that involves a change of connectivity.
Industry:Software
An isomerization is chemical reaction, the principal product of which is isomeric with the principal reactant. An intramolecular isomerization that involves the breaking or making of bonds is a special case of a molecular rearrangement.
Industry:Software
Stereoisomerization is isomerization resulting in a different spatial arrangement of atoms without any differences in connectivity or bond multiplicity between the isomers.
Industry:Software
Torsional Stereoisomerization is isomerization resulting in a different spatial arrangement of atoms arising from actual or conceptual torsion about a bond axis (including a double bond).
