Abstract

Abstract The strong preference of the S [DOUBLE BOND] O bond in trimethylene sulfite for an axial position (chair conformation), may not always prevent the molecules from occurring also in other conformations. A highly polar form having an equatorial S [DOUBLE BOND] O bond may show up in polar solvents, due to a favourable interaction energy, and supported by eg an a [RIGHTWARDS ARROW] e change of a tert.-butyl group.
