    Abstract: A process for the preparation of a 4-arylthioaniline from the corresponding 4-unsubstituted aniline which comprises reacting the latter with an alkali metal thiocyanate in the presence of halogen to provide the 4-thiocyanoaniline, reacting it with an alkali metal sulfide to convert the thiocyano moiety to an alkali metal mercaptide group followed by heating with cuprous oxide then with an aryl halide to form the desired product.

    Abstract: Perhaloalkanesulfenyl chlorides are reacted with aldehydes and ketones to provide novel (perhaloalkyl)thio-substituted aldehydes and ketones which are useful organic solvents and intermediates. As intermediates, these compounds are especially useful in the preparation of their carbamate derivatives which have pesticical utility.

    Abstract: The compounds 1-trifluoromethylthio-3,3-dimethyl-2, butanone-O-methylcarbamoyloxime and 1-difluoromethylthio-3,3-dimethyl-2-butanone-O-methylcarbamoyloxime are prepared from certain novel ketone and oxime intermediates. These compounds have insecticidal activity and are particularly effective against the Western and Northern corn rootworms, Diabrotica virgifera and Diabrotica longicornis respectively.
