Abstract:
Fungicidal cyanophenyl sulfoxides and sulfones having the formula:
WHEREIN M IS 1 OR 2; N IS 1 OR 2; P IS 2, 3 OR 4; R is an alkyl or alkenyl group having 1 to 4 carbons and substituted with zero to two -Br, -Cl or F radicals; and X is -Br or -Cl, independently in each occurrence. The dicyano compounds are more active and are accordingly preferred. The disclosed compounds are of particular utility as paint film preservatives and microbicides.
WHEREIN X represents hydrogen, chloro or bromo and R represents X or thioalkylthiocyanato (-SCH2SCN). These compounds have been found to be useful as bactericides and fungicides.
WHEREIN X represents chloro or bromo and n represents an integer of 2 to 4, are prepared. These compounds have been found to be useful as bactericides and fungicides.
Abstract:
DISCLOSED AS NOVEL COMPOUNDS ARE POLYHALO-4-NITROPYRIDINE DERIVATIVES WHICH ARE SUBSTITUTED IN THE 6-POSITION BY CYANO, TRIFLUOROMETHYL OR METHYLSULFONYL GROUPS. THE COMPOUNDS HAVE UTILITY AS PESTICIEDS AND ARE VARIOUSLY EFFECTIVE AS HERBICIDES AND AS ACTIVE CONSTITUENTS FUNGICIDAL AND BACTERIOCIDAL COMPOSITIONS.

Abstract:
A process is disclosed for converting aromatic thiols to the corresponding nitroso- or nitro-substituted compounds by treating the thiol compounds with an excess of nitric acid having a HNO3 concentration of 90 to 100 percent. Representative starting compounds are benzenethiols and pyridinethiols which, in addition to the thiol group, are substituted with one or more electronwith-drawing groups such, for example, as chloro, nitro or cyano, among others. The nitroso and nitro compounds produced during the reaction have utility as pesticides and are variously effective as herbicides and in the control of fungi and nematodes as well as of parasites infecting warmblooded animals.
