Abstract: Novel N-haloalkanesulfenylcarbamoyloxime compounds have been found to have exceptional miticidal and insecticidal activity.

Abstract: A new series of substituted esters of 3-hydroxyindone compounds have been found to have exceptional miticidal and herbicidal activity.

Abstract: New derivatives of amino acids which have the general formula ##STR1## are useful as angiotensin converting enzyme inhibitors.

Abstract: Certain derivatives of cyclopropane carboxylic acid and their esters are useful and valuable intermediates for the preparation of broad spectrum pyrethroid type pesticides. The invention provides a novel method for the preparation of the derivatives of cyclopropane carboxylic acid and esters from stable sulfonium ylides.

Abstract: Mercaptans are prepared by reacting an organic chloride or bromide with a mixture of H.sub.2 S and ammonia or an amine at a temperature of 0.degree. to 175.degree. C. under autogenous pressure. The reaction can be carried out in the presence of a polar solvent. For example, 3-chloropropyltrimethoxysilane is mixed with H.sub.2 S and ammonia in methanol and heated in a closed container at 100.degree. C. for 18 hours.

Abstract: This invention is directed to novel halogen-containing polythiols which impart improved flame retardancy to radiation cured thiol-ene compositions.

Abstract: Stabilizer mixtures that are capable of enhancing the resistance of polyolefins to degradation as a result of exposure to light and air, particularly at elevated temperatures, are obtained by reacting an .alpha.-olefin with an ester of a mercaptocarboxylic acid and a polyhydric alcohol, forming a reaction product of unknown structure containing thioether groups and carboxylic acid ester groups.

Abstract: 2-Amino-(2)-thiazoline-4-carboxylic acid is prepared by dehydrochlorinating S-(.beta.-carboxy-.beta.-chloroethyl) isothiourea by adding it to an aqueous medium maintained at a pH ranging from 5.5 to 7.5 with an alkali.

Abstract: A new method of preparing trifluoromethylthioacetic acid using a tertiary phosphine in a sulfur extrusion of lower alkyl trifluoromethyldithioacetate with optional is situ alkaline hydrolysis of said acetate using a biphasic hydrolysis system in the presence of a phase transfer catalyst.

Abstract: A process is provided for the preparation of mercapto propionic acid esters and/or polythio dipropionic acid esters by reaction of an acrylic acid ester with hydrogen sulfide in the presence of a weakly basic amine as a catalyst, a polythiodipropionic acid ester as a reactive solvent, and added elemental sulfur.

Abstract: Ketoalkanesulfenylcarbamoyl and ketoalkanethiosulfenylcarbamoyl halides are useful intermediates in the preparation of pesticidally active carbamates.

Abstract: A pleuromutilin derivative which is 14-desoxy-14-thiocyanatoacetoxy-mutilin is useful as an animal feed additive to increase meat production and also finds application in veterinary medicine as an antibiotic.

Abstract: Symmetric azo-bis-mercapto compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are methyl or ethyl, R.sub.3 and R.sub.4 are the same or different alkylene having 1 to 4 carbon atoms, and n is 0 or 1, and a method for forming block copolymers of vinyl monomers in a two-step process employing such compounds as polymerization initiators.

Abstract: A process is provided for the preparation of mercapto propionic acid esters and/or polythio dipropionic acid esters by reaction of an acrylic acid ester with hydrogen sulfide in the presence of a weakly basic amine base as a catalyst and a polythiodipropionic acid ester as a reactive solvent.

Abstract: This invention is directed to novel halogen-containing polythiols which impart improved flame retardancy to radiation cured thiol-ene compositions.
