Abstract :
Smog chamber/FTIR techniques were used to study the kinetics and mechanism of the reaction of Cl atoms with iodobenzene (C6H5I) in 20–700 Torr of N2, air, or O2 diluent at 296 K. The reaction proceeds with a rate constant k(Cl+C6H5I)=(3.3±0.7)×10−11 cm3 molecule−1 s−1 to give chlorobenzene (C6H5Cl) in a yield which is indistinguishable from 100%. The title reaction proceeds via a displacement mechanism (probably addition followed by elimination).
