Conclusions

  1. 1.

    By graphic processing of the dipole moments of cis-2-aryl-4-R-1,3-dioxa-5,6-benzo-cycloheptenes replacement of the H atom by Me(Ph) at C-4 was shown not to change the position of chair-twist equilibrium.

  2. 2.

    The chair-chair conformational energy and the enthalpy component of the Ce~Te conformation energy for the 4-methyl group were determined.
