摘要:
A process for the transvinylation of a vinyl derivative of a Bronsted acid with a different Bronsted acid which comprises providing a liquid phase mixture containing said vinyl derivative and said Bronsted acid in the presence of a ruthenium compound at a temperature at which transvinylation occurs and recovering as a product of transvinylation the vinyl derivative of the different Bronsted acid. The process is most favorably employed using carboxylic acids to make vinyl esters of carboxylic acids.

摘要:
Certain substituted cyanobenzenesulfonamides, nitrobenzenesulfonamides, trifluoromethylbenzenesulfonamides, halobenzenesulfonamides, and cyanomethylbenzenesulfonamides are effective preemergence and postemergence herbicides, which may be used for selective weed control in certain crops.
摘要:
NOVEL SUBSTITUTED BENZENESULFONAMIDES ARE USEFUL AS AGENTS FOR THE TREATMENT OF BOTH MATURE AND IMMATURE LIVER FLUKE INFECTIONS. THE BENZENESULFONAMIDE IS SUBSTITUTED ON THE SULFONAMIDE NITROGEN WITH LOWERALKOXY, SUBSTITUTED LOWERALKYL AND HETEROCYCLIC IN WHICH THE SULFONAMIDE NITROGEN IS INCLUDED IN THE HETEROCYCLIC RING. THE BENZENE RING IS VARIOUSLY SUBSTITUTED AT THE 3- AND 5-POSITIONS AND UNSUBSTITUTED OR SUBSTITUTED WITH AN AMINO GROUP AT THE 4-POSITION. CMPOSITIONS CONTAINING THESE COMPOUNDS FOR THE TREATMENT OF MATURE AND IMMATURE LIVER FLUKE INFESTATION ARE ALSO DISCLOSED.

NUCLEAR SULFAMOLY AND NUCLEAR SULFONYL SUBSTITUTED NORGANOSULFONYL BENZAMIDES AND SALTS THEEOF WHEREIN THE BENZENE RING MAY BE EITHER UNSUBSTITUTED OR SUBSTITUTED BY ONE OR MORE LOWER ALKYL, HALO, TRIHALOMETHYL, NITRO, CARBOXY, AMINO, HALOSULFONYL, ALKYLSULFONYL OR SULFAMOYL RADICALS. THE PRODUCTS ARE PREPARED BY TREATING A NUCLEAR SULFAMOYL- (OR SULFONYL)SUBSTITUTED BENZOYL HALIDE WITH AN ORGANOSULFONAMIDE OR SALT THEREOF. THE PRODUCTS ARE USEFUL AS URICOSURIC AGENTS IN THE TREATMENT OF GOUT AND GOUTY ARTHRITIS.
摘要:
The invention relates to new substituted biphenyl acetic acids and derivatives thereof. These novel compounds are useful as antiinflammatory agents and for the control of arthritic conditions.
