| Résumé : | The order of mobility of the halogens in the reaction of 1‐halo‐2,4‐dinitro‐benzenes and 1‐methyl‐2‐halo‐3,5‐dinitro‐benzenes with potassium iodide in dry acetone is shown to be F < Cl < Br. The ratio of reactivities evaluated from kinetic constants is approximately F : Cl : Br = 0,06: 1: 120 (cf Part I, this bull. 64, 700 (1955), for kinetic data concerning the bromo‐compounds). Arrhenius parameters have been determined for the reaction, in the case of 1‐chloro‐2,4‐dinitro‐benzene and 1‐methyl‐2‐chloro‐3,5‐dinitrobenzene. The synthesis of 1‐methyl‐2‐fluoro‐3,5‐dinitro‐benzene is described. Copyright © 1955 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim |
