Mechanism of the pyrolysis of 3-bromopentane
Abstract
The gas-phase dehydrobromination of 3-bromopentane has been shown to be a homogeneous first-order reaction, unaffected by the presence of cyclohexene. The rate constants follow the Arrhenius equation k1= 1013 · 51 exp(–45,440/RT). These observations are consistent with a molecular mechanism but not with the chain mechanism for bromide pryolysis proposed by Wojciechowski and Laidler.
