Reactive scattering of F atoms with C6H5Br and C6H5I molecules leading to both hydrogen and halogen atom displacement has been studied at an initial translational energy E similar to 38 kJ mol(-1) using a supersonic beam of F atoms seeded in He buffer gas. The center-of-mass angular distributions of C6H5F reactive scattering show symmetrical forward and backward peaking, which is consistent with a long-lived collison complex, but the product translational energy distributions peak at a fraction f’(pk) similar to 0.18 of the total available energy and lie well above the predictions of phase space theory. The branching ratio similar to 4 favors halogen atom over hydrogen atom displacement. The H atom displacement pathway is impeded by a potential energy barrier and occurs in competition with atom migration around the benzene ring. The halogen atom displacement occurs directly an F or H atom becomes bonded to the carbon atom adjacent to the halogen atom, following F atom or possibly H atom migration from other locations on the ring. The H atom displacement pathway for both FC6H5Br and FC6H4I reaction products shows a nominally isotropic angular distribution and a product translation energy distribution peaking at a fraction f’(pk) similar to 0.2 Of the total available energy, in line with the H atom displacement dynamics previously observed for F + C6H5Cl.
