AbstractDie Produkte der Sulfochlorierung (Einwirkung von Chlor und SO, in CCl4 bei 0‐5°C unter Belichtung) von Alkylchloriden (I) werden mittels 1 H‐ und 13C‐NMR‐Spektroskopie untersucht.

Studies on Sulphochlorination of Paraffins. V. Kinetic Studies on the Sulphochlorination of Pure AlkanesulphochloridesThe mixtures of disulphochlorides formed by sulphochlorination of 1‐alkanesulphochlorides C4C9 may be analyzed gaschromatographically after transformation into the corresponding dimethylamides. The individual peaks could be identified in some cases with the aid of pure isomeric disulphochlorides, in other cases they were identified by analogy. The mixtures formed by sulphochlorination of the isomeric heptane sulphochlorides also could be analyzed after transformation into the dimethylamides; the identification of all peaks was possible by comparison of the mixtures obtained from different heptane sulphochlorides.For the alkane sulphochlorides studied the relative rates of sulphochlorination (with reference to n‐octane) were determined, and therefore the relative reaction rates of the individual CH‐bonds with reference to one primary CH‐bond of n‐octane could be calculated.The results show a geminal or vicinal disubstitution not to take place in noticeable amount. In position 3 or in greater distance the influence of the sulphochloride group on the reactivity of the CH‐bonds is not significant.
