Terminal Alkyne-Assisted One-Pot Synthesis of Arylamidines: Carbon Source of the Amidine Group from Oxime Chlorides
A terminal alkyne-assisted protocol for the one-pot formation of a diverse range of arylamidines from a novel cascade reaction of in situ generated nitrile oxides, sulfonyl azides, terminal alkynes, and water by [3 + 2] cycloaddition and ring opening sequ
Sulfonyl azides acylsulfonamide derivatives and their use for production of derivative.
PROBLEM TO BE SOLVED: To provide a click reaction having bioorthogonality and high versatility.SOLUTION: Sulfonyl amidines and acylsulfonamides are manufactured by using thioamide and sulfonyl azide. The reaction is a novel click reacting having no need of additives and bioorthogonality and high versatility with proceeding under a mild condition and in a solution.

Coupling reaction of thioamides with sulfonyl azides: An efficient catalyst-free click-type ligation under mild conditions
We report a coupling reaction of thioamides and sulfonyl azides to generate sulfonyl amidines in the absence of any activation additives. The reaction progresses in various solvents under mild conditions. Water exhibits the highest performance with respect to efficiency.
N-Perfluoroalkylsulfonylimido derivatives of arenecarboxylic acid amides and their oxidative aza Hofmann rearrangement
The analogues of carboxamides in which the sp2-hybridized oxygen atom is replaced by more electron-withdrawing groups, {double bond, long}NSO2CF3 and {double bond, long}NSO2C4F9, have been

N2-(ARYLSULFONYL)ARYLAMIDINES. SYNTHESIS AND PROPERTIES OF N2-(ARYLSULFONYL)ARYLAMIDINES AND THEIR N1-ACYL DERIVATIVES
The reaction of carboxylic acid chlorides with N2-(arylsulfonyl)benzamidines was investigated.Conditions were found for the production of N2-arylsulfonyl-N1-acylbenzamidines and N2-arylsulfonyl-N1,N1-diacylbenzamidines.The hydrolysis and ammonolysis of the compounds were studied, and their IR spectra are discussed.It was established that the reactin of arenesulfonamides with the nitriles of aromatic acids in the presence of the alkaline or acidic catalysts leads to the formation of N2-(arylsulfonyl)amidines.
