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: 3,5,7-Triaza-1-azoniatricyclo(3.3.1.1.sup.3,7)-decane:1-(2-phenoxyethyl)-, bromides are disclosed. These compounds have utility as antimicrobials and herbicides.

Abstract: Oxybis(4,1-phenylene(2-oxo-2,1-ethanediyl)) thiocyanate is prepared by reacting diphenyl oxide with chloroacetyl chloride and reacting the intermediate formed thereby with potassium thiocyanate. The compound has antimicrobial utility.

Abstract: (Isothiocyanatomethoxy)-1,1'-biphenyl compounds are disclosed. These compounds have utility as antimicrobials, herbicides, fungicides, and insecticides.

Abstract: Chloro-pyridinyloxymethyl esters of thiocyanic acid of the formula ##STR1## WHEREIN N IS 1 TO 4, M IS 1 TO 3, X is H, F, CCl.sub.3 or OCH.sub.2 Cl and the total number of substituent groups is no greater than 5. The compounds have fungicidal activity. The compounds are prepared by mixing a corresponding chloropyridine with sodium methoxide in methanol as reaction medium to form a corresponding chloro-methoxy pyridine, gradually adding to it sulfuryl chloride as a solution in carbon tetrachloride to form the corresponding chloromethoxy-chloropyridine and adding thereto potassium thiocyanate to form product chloropyridinyloxymethyl ester of thiocyanic acid.
