<P> A 1 , 2 - rearrangement or 1 , 2 - migration or 1 , 2 - shift or Whitmore 1 , 2 - shift is an organic reaction where a substituent moves from one atom to another atom in a chemical compound . In a 1 , 2 shift the movement involves two adjacent atoms but moves over larger distances are possible . In the example below the substituent R moves from carbon atom C to C . </P>
