With the help of nonempirical quantum-chemical approximations we have studied the conformational equilibria in a series of 4-substituted 1,3,2-dioxaborinanes. It is shown that the route includes minima corresponding to the equatorial and axial sofa forms, and maxima corresponding to the equatorial and axial 2,5-twist conformations.
