Abstract: 5,6-Dihydro-2-methyl-1,4-oxathiin derivatives are prepared by chlorinolysis of an appropriate 1,3-oxathiolane derivative to generate alkene-sulfenic acid, followed by cyclization and loss of hydrogen chloride to form said product.

Abstract: This method of making 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide is based on the use of an oxathiolane, namely, 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide, which may be formed by condensing 2-mercaptoethanol with acetoacetanilide under acidic conditions in a solvent medium (aromatic hydrocarbon, chlorinated hydrocarbon or alkyl ester of an aliphatic acid). The said oxathiolane, with or without purification, is reacted with hydrogen peroxide in water or in a water-organic solvent mixture under basic conditions in the presence of a catalytic amount of a metal compound such as sodium tungstate to form 2-methyl-N-phenyl-1,3-oxathiolane-2-acetamide 3-oxide.

Abstract: Unsymmetrical N-substituted bis-carbamoyloxy disulfide compounds exhibit outstanding nematocidal, miticidal and insecticidal activity, coupled with substantially reduced mammalian toxicity and phytotoxicity as compared to known pesticidal compounds having a comparable spectrum of activity against insect, arachnid and nematode pests.

Abstract: Unsymmetrical bis-arylcarbamate disulfide compounds exhibit outstanding miticidal and insecticidal activity, coupled with substantially reduced mammalian toxicity and phytotoxicity as compared to known pesticidal compounds having a comparable spectrum of activity against insect and mite pests.
