Metal-free synthesis of sulfonamides via iodine-catalyzed oxidative coupling of sulfonyl hydrazides and amines

A novel, rapid, and environmentally-friendly protocol for the synthesis of sulfonamides using iodine as catalyst under solvent-free conditions is described. This method involves the oxidative coupling of sulfonyl hydrazides and amines in the presence of catalytic amount of iodine using TBHP as oxidant. This protocol does not require purification techniques such as column chromatography and recrystalization.

N-(phenylsulfonyl)picolinamide derivatives, process for producing the same, and herbicide

A herbicide containing as the active ingredient an N-(henylsulfonyl)picolinamide derivative represented by general formula (I) wherein X reprcsents a halogeno, a C1-4 alkyl, a C1-4 haloalkyl, a C1-4 alkoxy, a C1-4 haloalkoxy, a (C1-4 alkoxy)carbonyl, a [di(C1-4 alkyl)amino]sulfonyl, an [N—(C1-4 alkyl)-N—(C1-4 alkoxy)amino]sulfonyl, a (C1-4 alkylamino)sulfonyl, a C1-4 alkylthio, a C1-4 alkylsulfinyl, a C1-4 alkylsulfonyl, or nitro; n is an integer of 0 to 5; Y represets a halogeno, a C1-4 alkyl, a C1-4 haloalkyl, a C1-4 alkoxy, C1-4 haloalkoxy, a C1-4 alkylthio, a C1-4 haloalkylthio, amino, a C1-4 alkylamino, a di(C1-4 alkyl)amino, a (C1-4 alkoxy) C1-4 alkyl, a (C1-4 alkylthio) C1-4 alkyl, or nitro; and m is an integer of 0 to 4. This active ingredient is synthesized by condensing a substituted picolinic acid with a substituted benzenesulfonamide under dehydration, or by reacting the phenyl ester of a substituted picolinic acid with a substituted benzenesulfonamide in the presence of a basic compound.

Azo coupling of o- and p-(dialkylaminosulfonyl)benzene-diazonium salts with 7-acetylamino-4-hydroxynaphthalene-2-sulfonic acid in citrate-phosphate buffer solution

Dependences of the partial rate constants for azo coupling of o-(dialkylaminosulfonyl)benzene-diazonium salts with 7-acetylamino-4-hydroxynaphthalene-2-sulfonic acid (N-Acetyl-I-acid) on the fraction of the dianionic form of the latter indicate considerable steric hindrances to the second stage of the reaction. Ionization of the hydroxy group of N-acetyl-I-acid gives rise to additional electrostatic repulsion at the stage of formation of the σ complex, which reduces the rate of azo coupling at the 3-position of orthanilic acid.
