Abstract

In the temperature range 665–737 K the thermal decomposition of 1-methoxy-1- methylcyclopropane follows first-order kinetics with a rate constant given by the equation, k/s– 1= 1014.76±0.81 exp (–252±10 kJ mol–1/RT). The presence of the 1-methyl substituent destabilises the transition state for reaction. Secondary decomposition of the initially formed isomeric products precludes the determination of their individual rates of formation. Cis- ...
