Reaction of pentafluoroethyl radicals with cyanogen chloride
Abstract
The reaction of C2F5 radicals with cyanogen chloride was studied between 293 and 573 K, using perfluoroethyl iodide as the free-radical source.
The main product, C2F5Cl, is formed via an addition reaction or by abstraction of a chlorine atom by C2F5. The reactions involved are C2F5+ ClCN → C2F5Cl + CN (2), C2F5+ ClCN ⇌ C2F5ClCN (3), C2F5+ ClCN → C2F5Cl + CN (4), C2F5+ C2F5 [graphic omitted] C4F10.
The Arrhenius plot shows pronounced curvature. The following rate constants were obtained for reaction (2) and (4) log [(
The results are compared with those for the reaction of CF3 with ClCN.
