N2  - Ethyl N,N-dimethylcarbamate thermolyses to, N,N-dimethylamine, carbon dioxide, and ethylene in a homogeneous molecular reaction. First-order rate constants are described in s-1 units by the equation                             log k = 12.10-(44340±400)/&#952;   where &#952; = 4.576T. The pattern of substituent effects for N-substitution and values of &#916;S? for several N-substituted carbamates show that ring closure through the carbonyl oxygen is favoured over the alternative cyclization involving the nitrogen atom.
