Specificities of the Sulfur Version - Kinetics Versus Thermodynamics 

The remarkable feature that emerged from the 1970s reports was that the thio-Qaisen rearrangement is more facile in kinetic terms than the oxygen analogue. Two studies gave access to activation parameters. The group of Brandsma [25] and 

Other examples of retro-Claisen rearrangement were observed in the aromatic quinoline series [30] and with bicychc systems [31, 32]. Some specific cases have been predicted by calculations to be endothermic [33, 34].
