Rearrangement reaction  From Wikipedia, the free encyclopedia
Jump to: navigation, search  A rearrangement reaction are
organic reactions where the carbon skeleton of a molecule is
rearranged. The result is a structural isomer of the original
molecule.[1] Often a substituent moves from one atom to another
atom in the same molecule. In the example below, the substituent
R moves from carbon atom 1 to carbon atom 2:  General scheme
rearrangement  Intermolecular rearrangements also take place.
Isochorismate Pyruvate Lyase converts Isochorismate into
salicylate and Pyruvate  Sometimes chemists draw diagrams with
arrows that show how electrons are transferred between bonds
during a rearrangement reaction. Many organic chemistry text
books have such diagrams. But they do not tell the full story of
the reaction mechanism. The actual mechanism of a rearrangement
with an alkyl group moving is for the group to slide smoothly
along a bond, not ionic bond-breaking and forming. One example
of this is the Wagner-Meerwein r
