Abstract: (Polychlorophenoxy)methyl esters of thiocyanic acid of the formula ##STR1## WHEREIN X is hydrogen or chloro. The compounds are prepared by reacting substantially equimolar proportions of the appropriate polychloroanisole with phosphorous pentachloride at an elevated temperature to form the corresponding .alpha.,polychloroanisole and reacting the latter with potassium thiocyanate in an appropriate solvent at reflux temperature and recovering the (polychlorophenoxy)methyl ester of thiocyanic acid. The compounds have fungicidal and marine antifoulant activity.

Abstract: Chloral hydrate bis-ester of 2,2,3-trichloropropionic acid, CCl.sub.3 CH(OCOCCl.sub.2 CH.sub.2 Cl).sub.2, its preparation by reacting chloral hydrate with 2,2,3-trichloropropionyl chloride and herbicidal compositions containing chloral hydrate bis-ester of 2,2,3-trichloropropionic acid.

Abstract: Bromine chloride is contacted with a normally unreactive olefin such as 1,2-di, tri- or tetrahalo- ethylene or 1,2-di, tri- or tetraphenyl ethylene or 1-halo-2-phenyl ethylene or 1-halo-2-phenyl ethylene carrying in addition, one or more other halogen or phenyl substituents on the carbons of the double bond in a two-phase, aqueous-organic reaction medium containing a bromide salt dissolved in the aqueous phase to produce the dibrominated adduct of the olefin. By the process of the invention, tetrachloroethylene was brominated to give a 77% yield of 1,2-dibromotetrachloroethane.
