Conformation of 5-chlorotrimethylene selenite

Abstract

5-Chlorotrimethylene selenite, with mp 157-159°, is the trans-isomer, in which in the liquid form and in solution is realized a dynamic equilibrium of two forms, diaxial and diequatorial, with a predominance of the less polar form. The more polar conformer is realized in the crystalline state. © 1978 Plenum Publishing Corporation.
