What is a sigmatropic rearrangement?
An interesting group of pericyclic reactions involves the migration of a sigma bond from one site to another within the same molecule. Such reactions are called sigmatropic rearrangements.
What is a sigmatropic reaction?
Definition A sigmatropic reaction in organic chemistry is a pericyclic reaction (a pericyclic reaction is a type of organic reaction wherein the transition state of the molecule has a cyclic geometry, and the reaction progresses in a concerted fashion.
What is a walk rearrangement?
– In a bicyclic molecule, the migration of a divalent group, which is a part of 3-membered ring, is preferred as a “walk rearrangement”. 6. [2,3] Sigmatropic rearrangement: – Classified in 2 types: rearrangement of carbanions or rearrangement of ylides – Proceed through a 5-membered cyclic transition state.
