Cs2CO3 catalyzed rapid and efficient conversion of amines into sulfonamides; Alcohols and phenols into sulfonic esters

A simple and efficient method has been developed for the sulfonylation of several amines, alcohols, and phenols by p-toluenesulphonylchloride (p-TsCl) in the presence of catalytic amount of Cs2CO3 at 25C to obtain sulfonamides and sulfonic esters in very good yields. Cs2CO3 has been found to be highly efficient catalyst. Taylor & Francis Group, LLC.

Electroreductive nucleophile acceptor generation. Electrochemical synthesis of N-(4-(dimethylamino)phenyl)benzenesulfonamide

To the best of our knowledge, this is first report describing generation of Michael acceptor via electrochemical reduction. In this work, electrochemical reduction of 4-nitroso-N,N-dimethylaniline has been studied in the presence of arylsulfinic acids in

Chemical and electrochemical oxidative coupling of N,N-dialkyl-p- phenylenediamines and arylsulfinic acids. Synthesis of sulfonamide derivatives

Electrochemical and chemical oxidation of N,N-dialkyl-p-phenylenediamines have been studied in the presence of arylsulfinic acids as nucleophiles in aqueous solutions for the synthesis of sulfonamide derivatives. The results indicate that the electrochemi

Polycationic states of oligoanilines based on Wurster's blue

Polycations of two oligoanilines based on Wurster's blue, N,N',N-tris[4-(dimethylamino)phenyl]-N,N',N-trimethyl1,3,5-benzenetriamine (2) and N,N'-bis(3-{N-[4-(dimethylamino)phenyl]-N-methylamino}phenyl)-N,N'-dimethyl- pphenylenediamine (3), have been generated efficiently by a stepwise oxidation procedure, Their redox behavior was characterized in terms of the embedded p-phenylenediamine (PD) units and their intramolecular connectivity, EPR analysis of the oxidized 2 and 3 species revealed the existence of high-spin species in solution. It was found that spin multiplicities of the dominant polycationic species of 2 and 3 formed by 3 equiv, of oxidant can be assigned to quartet: and doublet states, respectively on the basis of pulsed EPR spectroscopy, These results demonstrate that the intramolecular connectivity between the spin-containing units decisively influences the spin preference of the multispin systems based on oligoanilines.

A simple and efficient method for sulfonylation of amines, alcohols and phenols with cupric oxide under mild conditions

Cupric Oxide efficiently catalyzed the synthesis of sulfonamides and sulfonic esters. This method has been applied to a variety of substrates including nucleophilic and sterically-hindered amines, alcohols and phenols with excellent yields of sulfonamides and sulfonic esters. The remarkable selectivity under mild and neutral conditions of this commercially available inexpensive catalyst is an attractive feature of this method.

Mild and efficient indium metal catalyzed synthesis of sulfonamides and sulfonic esters

A facile and efficient method for synthesizing sulfonamides was developed using a catalytic amount of indium metal. A wide range of sulfonamides were synthesized in excellent yields using the new process. The method showed a generality for substrates including less nucleophilic and sterically hindered anilines, and it is also applicable for preparing sulfonic esters from sulfonyl chlorides and alcohols.
