Abstract:
Carboxyalkyl dithiocarbamates which can be characterized by the formula ##STR1## wherein R is selected from the group consisting of alkylene radicals, preferably alkylene radicals each having from 1 to 4 carbon atoms, wherein R' is selected from the group consisting of hydrogen and methyl and ethyl radicals, and wherein X is selected from the group consisting of alkali metal atoms, their use as ore flotation suppressants, and a process for making these novel compositions are disclosed.
Abstract:
N-Arylthiolcarbamates for the formula ##STR1## where R denotes methyl or ethyl, X denotes halogen, Y denotes alkyl, haloalkyl of at least 2 carbon atoms, alkoxyalkyl, cycloalkyl, alkoxy or halomethoxy, and n denotes one of the integers 1 and 2, herbicides containing these compounds, and their use as herbicides.
Abstract:
Novel bis(dithiocarbamate) salts, the mixed transition metal salts, and zinc salt amine complexes thereof are claimed. These novel compounds have utility as antifungal agents.
Abstract:
An adduct of zinc chloride and benzyl-N,N-di-sec. butyl-thiolcarbamate, and use thereof as catalyst for preparing benzyl-N,N-di-sec.butyl-thiolcarbamate from carbamoyl chloride and benzyl mercaptan are disclosed.
Abstract:
Novel hydroxylalkyl dithiocarbamate of the formula ##STR1## wherein R.sub.1 represents a phenyloxyphenyl or phenylaminophenyl radical which is unsubstituted or substituted by lower alkyl, halogen, trifluoromethyl, nitro and/or cyano, and alk represents lower alkylene, are useful as anthelmintic agents.
Abstract:
The preparation of thiocarbamyl sulfenamides and particularly the preparation of disubstituted-thiocarbamyl cycloalkylsulfenamides may be improved by utilizing an excess of the dithiocarbamate solution which is reacted with the chlorocycloalkylamine and heating the reaction mixture for a short period of time.
Abstract:
HYDROCARBYL - HYDROXYVPHENYL - DIHYDROCARBYLDITHIOCARBAMATES AE PREPARED BY THE REACTION OF DIHYDROCARBYL HALOPHENOLS WITH A METAL SALT OF A DIHYDROCARBYLTHIOCARBAMATE. FOR EXAMPLE, THE REACTION OF 2,6-DI-TERT-BUTYL-4BROMOPHENOL WITH THE SODIUM ALST OF DIMETHYLDITHIOCARBAMATE YIELDS 3,5-DI-TERT-BUTYL-4-HYDROXYPHENYL DIMETHYL DITHIOCARBAMATE. THE COMPOUNDS ARE USEFUL AS ANTIOXIDANTS. EFFECTIVENESS IS ENHANCED BY DIHYDROCARBYL THIODIALKANOATES AND ORGANIC PHOSPHITES OR PHOSPHONATES.
Abstract:
New and valuable substituted thiolcarbamates having the formula IN WHICH R1 denotes a propargyl, cyanomethyl, Beta -cyanoethyl or Beta -chloro- Beta -cyanoethyl radical and R2 has the same meanings as R1, R1 and R2 being identical or different, and R2 may also denote a phenyl or cyclohexyl radical or an aliphatic radical having not more than six carbon atoms which may bear hydroxyl, chloro or thiocyano, lower alkoxythioether or lower alkylthioether groups as substituents and R3 denotes an aliphatic radical which may be substituted by halogen atoms. These compounds are effective herbicidal active ingredients which are particularly suitable for controlling unwanted grassy plants while leaving crop plants undamaged.
Abstract:

WHEREIN N IS AN INTEGER OF FROM 0 TO 5; X is selected from the group consisting of a halogen, an aliphatic radial, nitro, acyl, acyloxy, hydroxy and alkoxy; Y is selected from the group consisting of hydrogen, alkyl, phenyl and a carbamoyl radical of the formula:
WHEREIN R1 and R2 independently are selected from the group consisting of hydrogen, alkyl and phenyl; and Z is selected from the group consisting of an aliphatic radical, a cycloaliphatic radical, aryl and aralkyl. These compounds are useful as fungicides and nematocides.
