摘要
Computer simulation of the routes of conformational isomerization of 1,3,2-dioxathiane and its Soxides by nonempirical quantum-chemical method RHF/6-31G(d) revealed the main and local minima and transition states of this process. It was shown that the barrier of ring inversion is reduced in going from 1,3,2-dioxathiane to its oxides. The established Delta G (0) (300 K) value of S=O group in cyclic sulfite (-15.0 kJ mol(-1)) is in good agreement with the experimental data.
