Sigma reaction
Did you know?
A sigmatropic reaction in organic chemistry is a pericyclic reaction wherein the net result is one σ-bond is changed to another σ-bond in an uncatalyzed intramolecular reaction. The name sigmatropic is the result of a compounding of the long-established sigma designation from single carbon–carbon bonds … See more Woodward–Hoffman sigmatropic shift nomenclature Sigmatropic rearrangements are concisely described by an order term [i,j], which is defined as the migration of a σ-bond adjacent to one or … See more [1,3] shifts Thermal hydride shifts In a thermal [1,3] hydride shift, a hydride moves three atoms.
