- Visible-light-driven electron donor-acceptor complex induced sulfonylation of diazonium salts with sulfinates
-
This work reports an efficient sulfonylation reaction enabled by a visible-light-induced radical coupling reaction between phenyl/heterocyclic diazonium salts and sulfinates. Mechanistic experiments disclosed the formation of a versatile electron donor-acceptor (EDA) complex. This transformation is characterized by an easy operational procedure under mild conditions which avoids transition metals, ligands, catalysts, and oxidants.

- Sulfonylation of Bismuth Reagents with Sulfinates or SO2through BiIII/BiV Intermediates
-
Studies to explore the catalytic activities of main-group elements are attractive. We report here our study of sulfonylation of bismuth reagents with sulfinates or SO2 surrogates. Under oxidative conditions, triarylbismuthines and sulfinates were transformed into diaryl sulfones. A transition-metal-like two-electron redox process at the Bi center was achieved in this reaction. Sulfur dioxide generated in situ can also replace sulfinates to deliver the corresponding symmetric diaryl sulfones. A rational mechanism for this reaction was also proposed that involves a Bi(III)-Bi(V) manifold.

- Regiospecific Cleavage of S-N Bonds in Sulfonyl Azides: Sulfonyl Donors
-
Sulfonyl azides have been widely used as sulfonamido, diazo, and azido donors, as well as all-nitrogen 1,3-dipoles donors in synthetic chemistry. Here, the sulfonyl azides were used as efficient sulfonyl donors, which is very unusual. Trifluoromethanesulfonic acid-induced formation of the sulfonyl cation reactive species from sulfonyl azides was developed and used for the first time to couple various inactivated arenes to prepare sulfones at ambient temperature.

- Design, synthesis, characterization and antimicrobial evaluation of some heterocyclic condensed systems with bridgehead nitrogen from thiazolotriazole class
-
In the present study, a series of new heterocyclic condensed systems with bridgehead nitrogen from the thiazolo[3,2-b][1,2,4]triazoles class was synthesized starting from some 4-(4-X-phenylsulfonyl)phenyl)-4H-1,2,4-triazole-3-thioles 1a-c (X=H, Cl, Br). The intermediates of S-alkylated 1,2,4-triazoles, 2-(5-(4-(4-X-phenylsulfonyl)phenyl)-2H-1,2,4-triazol-3-ylthio)-1-(4-fluorophenyl)ethanones 2a-c, were obtained by treatment of triazoles 1a-c with 2-bromo-4'-fluoroacetophenone. The 2-(4-(4-X-phenylsulfonyl)phenyl)-6-(4-fluorophenyl)thiazolo[3,2-b][1,2,4]triazoles 3a-c were obtained by cyclization of S-alkylated 1,2,4-triazoles 2a-c in sulfuric acid media, at 0°C. For the synthesis of 2-(4-(4-X-phenylsulfonyl)phenyl)-5-(4-fluorobenzylidene)-thiazolo[3,2-b][1,2,4]triazol-6(5H)-ones 4a-c, the triazoles 1a-c were treated with 4-fluorobenzaldehyde, chloroacetic acid and anhydrous sodium acetate, in the presence of acetic acid and acetic anhydride. The structures of the newly synthesized compounds have been confirmed by elemental analysis and spectral methods (IR, 1H-NMR,13C-NMR, MS). The antimicrobial activity of all new compounds has been screened against some bacteria and yeasts.

- Sulfonylation of aromatic compounds with methyl p-toluenesulfonate as a sulfonylating precursor
-
We have developed Friedel-Crafts (FC) sulfonylation of aromatic compounds with methyl p-toluenesulfonate as a sulfonylating precursor. In this procedure, methyl p-toluenesulfonate was treated and activated with pyridine to produce N-methylpyridinium p-toluenesulfonate as a sulfonylation reagent. Reactivity of this salt for the sulfonylation of mesitylene was investigated in the presence of three different promoters, such as triflic anhydride, dimethylsulfide ditriflate, and triphenylphosphine ditriflate (TPPD). All of the promoters show chemoselectivity and among them, TPPD presents a chemoselectivity in FC sulfonylation. Iranian Chemical Society 2012.

The 1,2,4-triazoles were synthesized by intramolecular cyclization of acylthiosemicarbazides, in basic media. On the other hand, 1,3,4-thiadiazoles were obtained from same acylthiosemicarbazides, in acidic media. These new intermediates from thiosemicarbazide class were afforded by the reaction of 4-(4-X-phenylsulfonyl)benzoic acids hydrazides (X = H, Br) 1a,b with 4-trifluoromethoxyphenyl or 3,4,5-trimethoxyphenyl isothiocyanate.

- Copper(II) and uranyl(II) complexes with acylthiosemicarbazide: Synthesis, characterization, antibacterial activity and effects on the growth of promyelocytic leukemia cells HL-60
-
New chelates of N1-[4-(4-X-phenylsulfonyl)benzoyl]-N4-butyl-thiosemicarbazide (X = H, Cl, Br) with Cu2+ and UO22+ have been prepared and characterized by analytical and physico-chemical techniques such as magnetic susceptibility measurements, elemental and thermal analyses, electronic, ESR and IR spectral studies. Room temperature ESR spectra of Cu(II) complexes yield {g} values characteristic of distorted octahedral and pseudo-tetrahedral geometry. Infrared spectra indicate that complexes contain six-coordinate uranium atom with the ligand atoms arranged in an equatorial plane around the linear uranyl group. Effects of these complexes on the growth of human promyelocytic leukemia cells HL-60 and their antibacterial activity (against Staphylococcus epidermidis ATCC 14990, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 14579, Pseudomonas aeruginosa ATCC 9027 and Escherichia coli ATCC 11775 strains) were studied comparatively with that of free ligands.

- Unsymmetrical diaryl sulfones and aryl vinyl sulfones through palladium-catalyzed coupling of aryl and vinyl halides or triflates with sulfinic acid salts
-
The palladium-catalyzed reaction of sulfinic acid salts with a wide variety of aryl and vinyl halides or triflates provides unsymmetrical diaryl sulfones and aryl vinyl sulfones in good to excellent yields. The reaction is strongly influenced by the presence of nBu4NCl, and the use of Xantphos, a rigid bidentate ligand with a wide natural bite angle, was found to be crucial for the success of the reaction. With neutral, electron-rich, and electron-poor aryl iodides best results were obtained by using Pd 2(dba)3, Xantphos, Cs2CO3, and nBu4NCl, in toluene at 80 °C. Two general procedures were employed with aryl bromides and triflates: sodium p-toluenesulfinate, Pd2(dba)3, Xantphos, Cs2CO3, 120 °C, in toluene with nBu4NCl (procedure A: neutral, electron-rich, and slightly electron-poor aryl bromides or triflates) and without nBu4NCl (procedure B: electron-poor aryl bromides or triflates). With vinyl triflates best results were obtained at 60 °C omitting nBu4NCl.

A mild and efficient catalytic method for Friedel-Crafts sulfonylation of arenes to the corresponding sulfones using a catalytic amount of reusable solid acid and arene- or alkanesulfonyl chlorides, sulfonic anhydrides and sulfonic acids as sulfonylating agents is described. Solid acids enable formation of a sulfone by the reaction of a sulfonic acid and an arene for the first time. In pursuit of the development of the best catalytic system, various metal-exchanged K10 montmorillonites and synthetic zeolites such as zeolite beta, zeolite Y and ZSM-5 have been screened for Friedel-Crafts sulfone synthesis. Fe3+-montmorillonite in the family of clays and zeolite beta in the family of zeolites exhibit higher activity. The activity is correlated to the presence of the right mix of Bronsted and Lewis acidic sites. The regioselective sulfonylation of toluene and naphthalene are studied in which para and beta selectivities are observed respectively. The Royal Society of Chemistry 2000.
