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 migration is the intramolecular transfer of an atom or group during the course of a molecular rearrangement.
Industry:Software
A bond migration is the movement of a bond to a new position within the same molecular entity during the course of a molecular rearrangement.
Industry:Software
A substitution reaction is a reaction, elementary or stepwise, in which one atom or group in a molecular entity is replaced by another atom or group.
Industry:Software
A metathesis is a bimolecular process formally involving the exchange of a bond (or bonds) between similar interacting chemical species so that the bonding affiliations in the products are identical (or closely similar) to those in the reactants. (This is the definition in physical organic chemistry, requiring only one bond to be exchanged).
Industry:Software
A disproportionation is any chemical reaction of the type A + A → A' + A" where A, A' and A" are different chemical species. The splitting of a chemical compound into two new compounds, one more oxidized and one more reduced than the original compound.
Industry:Software
A radical disproportionation is a special case of disproportionation and is loosely described in organic chemistry as a chemical reaction between two radicals where the main feature is the transfer of one hydrogen atom from one chemical species to another with concomitant formation of an unsaturation in the first chemical species.
Industry:Software
A hydrogen exchange disproportionation is hydrogenation of a molecule by adding hydrogen to an unsaturated bond (making it less unsaturated) by transfer of hydrogen from another hydrocarbon.
Industry:Software
A group is a defined linked collection of atoms or a single atom within a molecular entity. (IUPAC 1997) (more) Note that a "group" is somewhat more specific or detailed than "substituent" or "ligand". "Substituents" can be composed of a collection of groups.
Industry:Software
A conformation is a distinct spatial arrangement of atoms that may convert to another conformation through rotation about a bond axis.
Industry:Software
Stereoisomers differ only in the spatial arrangements of their atoms. They are constitutionally identical. (same atoms and bond connectivity).
