Abstract:
There is provided a method for the preemergence and postemergence control of undesirable plant species by the application of a herbicidally effective amount of a 1,2,4-trialkyl disubstituted pyrazolium salt to the foliage of said undesirable plant species, and to soil containing seeds thereof.
Abstract:
Ketones are prepared by reacting an aromatic or heterocyclic aldehyde in the presence of a cyanide ion with an unsaturated compound having the formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are the same or different and are selected from the group of hydrogen, optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic, heterocyclic and carboxylic acid ester andR.sup.4 is nitrile (CN), --CO--R.sup.5 or --CO--OR.sup.5whereinR.sup.5 is selected from the group of optionally substituted aliphatic, cycloaliphatic, araliphatic, aromatic and heterocyclic andR.sup.1 and R.sup.2 and/or R.sup.1 and R.sup.3 and/or R.sup.2 and R.sup.5 or R.sup.3 and R.sup.5 together with the carbon atoms to which they are attached as substituents may also form a carbocyclic or heterocyclic ring.Ketones prepared according to the process of the invention have the formula: ##STR2## wherein R.sup.1 .sup.' and R.sup.3 .sup.' are identical or different and are selected from the group of hydrogen, lower alkyl having up to 3 C-atoms and optionally substituted phenyl; andR.sup.6 .sup.' is optionally substituted phenyl or a pyridyl.
Abstract:
There are provided novel 4-alkyl-1,2-dimethyl-3,5-diphenylpyrazolium compounds having fungicidal utility. There is also provided a method for both controlling fungi with a fungicidally effective amount of 4-alkyl-1,2-dimethyl-3,5-diphenylpyrazolium salt and protecting living plants from attack by fungi through the application to the foliage of said plants of a fungicidally effective amount of said pyrazolium salt.
Abstract:
The process involves the introduction of an organic group into an ethylenically unsaturated aldehyde or ketone. As an example, a mixture of diphenylmercury, lithium palladium chloride and acrolein is formed in acetonitrile as solvent. This results in the formation of an unstable adduct between the acrolein and phenylpalladium chloride. Decomposition of the adduct by maintaining it above its decomposition temperature provides cinnamaldehyde as the product.

R-C6H4-CH2-CH(-NH2)-C6H5
AN OPTICAL RESOLUTION METHOD FOR PREPARATION OF (+)TRANS-CHRYSANTHEMIC ACID WHICH COMPRISES USING AS A RESOLUTION AGENT A NOVEL AMINE REPRESENTED BY THE FORMULA,
Abstract:
One aspect of the present invention relates to ionic liquids comprising a pendant Bronsted-acidic group, e.g., a sulfonic acid group. Another aspect of the present invention relates to the use of an ionic liquid comprising a pendant Bronsted-acidic group to catalyze a Bronsted-acid-catalyzed chemical reaction. A third aspect of the present invention relates to ionic liquids comprising a pendant nucleophilic group, e.g., an amine. Still another aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to catalyze a nucleophile-assisted chemical reaction. A fifth aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to remove a gaseous impurity, e.g., carbon dioxide, from a gas, e.g., sour natural gas.
