Abstract:
The inclusion complexes of styrene and alpha-methyl-styrene with beta-cyclodextrin (beta-CD) were investigated by using [1H] NMR titration in solution and X-ray diffraction (XRD) analysis, thermo-gravimetric analysis (TGA), elemental analysis (EA) in the solid state. The inclusion process has been studied by using PM3 quantum-mechanical semi-empirical method. The calculated results are in agreed with the experimental data. All results show that alpha-methyl-styrene has stronger interaction with beta-cyclodextrin than styrene does, so the complex of beta-CD-alpha-methyl-styrene is more stable.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
