La Specificite des Halogenations Atomiques VII. La photochloruration du chloroforme

The photochemical reaction between Cl2 and CHCl3 has been studied. The experimental rate equation can be explained from the general scheme previously proposed and yields two relations between elementary rate constants. Further two relations are obtained from the competition reaction in a mixture of Cl2, CHCl3 and C2Cl4: (Formula Presented.) Arguments are given to reject a mechanism of the Rollefson type. The chain breaking step previously proposed by Schumacher is in contradiction with the experimental results. Copyright © 1958 Wiley‐VCH Verlag GmbH & Co. KGaA, WeinheimSCOPUS: ar.j
