Thermodynamic control reversibility tests

In Section 13.1, it was noted that implicit in the theory of kinetic and thermodynamic control is the fact that the kinetic product (Z in Fig. 13.1 and Y in Fig. 13.2), which is produced more rapidly, is also reconverted to starting material more rapidly. The thermodynamic product, on the other hand, being more stable, is not so readily reconverted to starting material. Experimental Procedure E provides tests of the relative stabilities of the two semicarbazone products toward the reverse reaction. The results of these experiments should provide additional evidence as to which of the semicarbazones is the product of kinetic control and which is the product of thermodynamic control.
