Antarafacial - suprafacial — Antarafacial and suprafacial are two topological concepts in organic chemistry describing the relationship between two simultaneous chemical bond making and/or bond breaking processes in or around a reaction center [IUPAC Gold Book definition… … Wikipedia
Sigmatropic reaction — A Sigmatropic reaction in organic chemistry is a pericyclic reaction wherein the net result is one sigma bond changed to another sigma bond [F.A. Carey, R.J. Sundberg, Advanced Organic Chemistry Part A ISBN 0 306 41198 9] . In this type of… … Wikipedia
Ene reaction — The Ene reaction (also known as the Alder ene reaction) is a chemical reaction between an alkene with an allylic hydrogen (the ene) and a compound containing a multiple bond (the enophile), in order to form a new σ bond with migration of the ene… … Wikipedia
Claisen rearrangement — The Claisen rearrangement (not to be confused with the Claisen condensation) is a powerful carbon carbon bond forming chemical reaction discovered by Rainer Ludwig Claisen. The heating of an allyl vinyl ether will initiate a [3,3] sigmatropic… … Wikipedia

Cycloaddition — A cycloaddition is a pericyclic chemical reaction, in which two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity. [1] The… … Wikipedia
Cicloadición — Una cicloadición es una reacción química pericíclica en la que dos enlaces π se pierden y se forman dos enlaces σ,[1] la reacción resultante es una reacción de ciclización. Las cicloadiciones suelen ser descritas por el tamaño del esqueleto de… … Wikipedia Español
Cope rearrangement — The Cope rearrangement is an extensively studied organic reaction involving the [3,3] sigmatropic rearrangement of 1,5 dienes.[1][2][3][4] It was developed by Arthur C. Cope. For example 3 methyl 1,5 hexadiene heated to 300°C yields 1,5… … Wikipedia
