Compounds formed by combining a carboxylic acid herbicide with N&#x2014;((C-C) alkyl or arylalkyl) tri((C-C) alkyl)ammonium hydroxide have herbicidal activity on an acid equivalent basis at least as active as the commercially used carboxylic acid herbicide salts, but are less volatile.

Compounds derived from herbicidal carboxylic acids and tetraalkylammonium or (arylalkyl)trialkylammonium hydroxides

Provided are methods for introducing a molecule of interest into a plant cell comprising a cell wall. Methods are provided for genetically or otherwise modifying plants and for treating or preventing disease in plant cells comprising a cell wall.

2-Substituted-5-(1-alkylthio)alkylpyridines are produced efficiently and in high yield by cyclization and thioalkylation.

Process for the preparation of 2-substituted-5-(1-alkylthio)alkylpyridines

New synthetic procedures for preparing insecticidal 3-(substituted phenyl)-5-(thienyl or furyl)-1,2,4-triazoles utilizing thioimidate intermediate.

Process for preparing 3-(substituted phenyl)-5-thienyl or furyl)-1,2,4-triazoles and novel intermediates utilized therein

1-Halo-2-chloro-3-alkoxy-4-alkylsulfonylbenzene and 1-halo-2,3-dichloro-4-alkylsulfonylbenzene compounds were converted to compounds having hydroxycarbonyl or alkoxycarbonyl substituents in place of the 1-halo substituent by reaction with carbon monoxide and water or an alcohol respectively, in the presence of a palladium II salt: trihydrocarbylphosphine complex type catalyst.

Process for preparing 2-chloro-3-alkoxy-4-alkylsulfonyl-benzoic acids and esters

Herbicidal 1-alkyl-4-(2-chloro-3-alkoxy-4-alkylsulfonylbenzoyl)-5-hydroxypyrazole compounds, as well as 1-halo-2-chloro-3-alkoxy-4-alkylsulfonylbenzene compounds and 2-chloro-3-alkoxy-4-alkylsulfonylbenzoic acid compounds, were prepared in good yield by the reaction of the corresponding 3-chloro compound with an alkali metal alkoxide compound. 1-Halo-2-chloro-3-alkoxy-4-alkylsulfonylbenzene and 1-halo-2,3-dichloro-4-alkylsulfonylbenzene compounds were converted to compounds having hydroxycarbonyl, alkoxycarbonyl, or 1-alkyl-5-hydroxypyrazole-4-carbonyl substituents in place of the 1-halo substituent by reaction with carbon monoxide and water, an alcohol, or a 1-alkyl-5-hydroxypyrazole compound, respectively, in the presence of a palladium II salt:trihydrocarbylphosphine complex type catalyst.
