β-Elimination of some solid ββ′-dihalogenoadipodinitriles with gaseous ammonia. An example of a non-topochemically controlled reaction

Abstract

The stereocourse of the reaction of solid dihalogenoadipodinitriles with gaseous ammonia has been investigated in terms of the conformation of the reacting molecules in the crystal; under the heterogeneous conditions of the reaction, in certain systems, an equilibrium between different rotamers occurs before an anti-type elimination takes place.
