Kinetics and Mechanism of 1,3-Cycloaddition of 3,4,5,6-Tetrachlorobenzene-2-Diazo-1-Oxide
Soon-Yung Hong
The effect of dimethyl maleate on the rate of thermolysis of 3,4,5,6-tetrachlorobenzene-2-diazo-1-oxide in 1-chloronaphthalene at 130.2° was investigated: In a separate experiment, the effect of dimethyl fumarate upon the same reaction at the same temperature was investigated. The rate of thermolysis was decreased by dimethyl maleate, while dimethyl fumarate accelerated the reaction. Some kinetic parameters of the thermolysis of 3,4,5,6-tetrachlorobenzene-2-diazo-1-oxide were calculated. A mechanism of isomerization of dimethyl maleate to dimethyl fumarate by 3,4,5,6-tetrachlorobenzene-2-diazo-1-oxide was proposed.
