Conclusions
-
1.
The influence of pressures up to 12,800 kg/cm2 and temperatures in the interval 60–140° on the isomeric composition of the adducts of diene condensation of trans-piperylene with methyl acrylate was investigated. The differences of the volumes, energies, and entropies of the corresponding transition states were calculated.
-
2.
The transition state is evidently structurally closer to a plane-parallel model of the prereaction-complex than to the structure of the adduct.
