comparable degree by both an unsubstituted double bond, and by bridge chlorines. Bridgehead chlorines have less effect on reactivity. The rate-determining step of reaction is likely to be attack by thiomethoxide ions on the chlorine-substituted double bond. The disubstitution product 1,4,7,7-tetrachloro-2,3-dithiomethoxynorborna-2,5-diene derived from hexachloronorbornadiene deteriorates on keeping, for

Differential kinetic behaviour in thermal dyotropic rearrangement of compounds containing a cyclohexa-1,3-diene ring as 2H donor held proximate to a variously-substituted norbornene element as acceptor is discussed in terms of parameters derived by single crystal X-ray structure analysis and Molecular Mechanics calculations.
