over. This latter process reduced the disulfide formed during the oxidation stage. The haloarylthiol wag extracted from the steam distillate with ether. The ether layer was dried over anhydrous sodium sulfate and the haloarylthiol recovered bv evaDoration of the ether and distillation. Table IV 1ist"s the haloarylthiola prepared by this method.
