Poly(N,N'-Dichloro-N-ethyl-benzene-1,3-disulfonamide) and N,N,N',N'-Tetrachlorobenzene-1,3-disulfonamide as efficient reagents to direct oxidative conversion of thiols and disulfide to sulfonyl chlorides

Poly(N,N'-Dichloro-N-ethyl-benzene-1,3-disulfonamide) (PCBS) and N,N,N',N'-Tetrachlorobenzene-1,3- disulfonamide (TCBDA) were found to be a mild and efficient reagent for the direct oxidative conversion of sulfur compounds to the corresponding arenesulfonyl chlorides in good to excellent yields through the oxidative chlorination. The overall process is simple, practical, and it provides convenient access to a variety of aryl or heteroarylsulfonyl chlorides. The mild reaction conditions and the broad substrate scope render this method attractive, and complementary to existing syntheses of aryl or heteroarylsulfonyl chlorides.

Poly(N,N'-dichloro-N-ethyl-benzene-1, 3-disulfonamide) and N,N,N',N'-Tetrachlorobenzene-1,3-disulfonamide as novel catalytic reagents for synthesis of Bis-indolyl, Tris-indolyl, Di(bis-indolyl), Tri(bis-indolyl) and Tetra(bis-indolyl) methanes under solid-state, solvent and water conditions

Easy and rapid preparation of bis-indolyl, tris-indolyl, di(bis-indolyl), tri(bis-indolyl) and tetra(bis-indolyl) methanes from indole with various aldehydes and ketones using poly (N,N'-dichloro-N-ethyl-benzene-1,3- disulfonamide) [PCBS] and N,N,N',N'-tetrachlorobenzene-1,3-disulfonamide [TCBDA] as novel catalysts under various conditions are here described.

Poly(N,N′-dichloro-N-ethylbenzene-1,3-disulfonamide) and N,N,N′,N′-tetrachlorobenzene-1,3-disulfonamide as novel reagents for the synthesis of N-chloroamines, nitriles and aldehydes

The applications of poly(N,N′-dichloro-N-ethylbenzene-1,3- disulfonamide) (PCBS) and N,N,N′,N′-tetrachlorobenzene-1,3- disulfonamide (TCBDA) as novel reagents for the preparation of N,N-dichloroamines, nitriles, and aldehydes from primary amines under various conditions are described. Also, a simple and effective procedure for the direct oxidative conversion of primary alcohols into nitriles was successfully carried out with TCBDA and PCBS in aqueous ammonia.

One-pot synthesis of substituted pyrroles with N, N, N', N' -tetrachlorobenzene-1, 3-disulphonamide and N, N'-diiodo-N, N' -1, 2-ethanediylbis(p-toluenesulphonamide) as novel catalytic reagents

In this research, N, N, N'N'-tetrachlorobenzene-1, 3-disulphonamide as novel catalytic reagent and 2V,2V'-diiodo-2V,2V'-1, 2-ethane- diylfeis(p-toluenesulphonamide) as new catalyst were used for the synthesis of V-substituted pyrroles in good to excellent yields under mild conditions. These reusable reagents were compared with existing reagents and it is clear that this study is a welcome addition in the field of pyrrole synthesis.
