The gase phase pyrolysis of o-hydroxy-2-phenethyl chloride in the temperature range of 370-420 deg C and pressure range of 64-196 torr is homogeneous and unimolecular.The reaction, under maximum inhibition of propene, obeys first order kinetics and the products are benzodihydrofuran, o-hydroxystyrene, and hydrogen chloride.The temperature dependence of rate coefficients is given by the Arrhenius equation: log k1 (s-1)=(13.85+/-0.53)-(225.7+/-9.9)(2.303RT)-1 kJ*mol-1.The phenolic OH group most probably participates in the elimination process, where dehydrochlorination and cyclic products result from an intimate ion pair type mechanism.The partial rates toward each of the parallel products are reported and discussed.
