Synthesis of optically pure 3,3'-diaryl binaphthyl disulfonic acids via stepwise N-S bond cleavage.

Hatano M, Ozaki T, Nishikawa K, Ishihara K.Author information Graduate School of Engineering, Nagoya University , and ‡Japan Science and Technology Agency (JST), CREST, Nagoya University , Furo-cho, Chikusa, Nagoya 464-8603, Japan.AbstractWe developed a practical synthesis of optically pure 3,3'-diaryl-1,1'-binaphthyl-2,2'-disulfonic acids (i.e., (R)- or (S)-3,3'-Ar2-BINSAs) from the parent chiral sulfonimides via stepwise N-S bond cleavage of the sulfonimides and the resultant sulfonamides. This unusual synthesis, which provides arylsulfonic acids from arylsulfonamides, is valuable since common methods particularly give amines with the decomposition of sulfone groups during deprotection.

Synthesis of [60]fullerene-fused sultones via sulfonic acid group-directed C-H bond activation.

Li F, Liu TX, Wang GW.Author information Hefei National Laboratory for Physical Sciences at Microscale, and Department of Chemistry, University of Science and Technology of China, Hefei, Anhui 230026, PR China.AbstractFunctionalization with the sulfonic acid group as the directing group in a C-H activation reaction has been revealed for the first time. [60]Fullerene has been employed in the unprecedented palladium-catalyzed C-H activation reaction of arylsulfonic acids to afford [60]fullerene-fused sultones.

Effective and selective bisphenol A synthesis on a layered silicate with spatially arranged sulfonic acid.

Ide Y, Kagawa N, Itakura M, Imae I, Sadakane M, Sano T.Author information Department of Applied Chemistry, Graduated School of Engineering, Hiroshima University, Higashi-Hiroshima, Japan. ysuke-ide@hiroshima-u.ac.jpAbstractThe silylated derivatives of a layered alkali silicate, magadiite, modified with propylsulfonic or arylsulfonic acid were synthesized and used as catalysts for an acid-catalyzed condensation of phenol with acetone. The propylsulfonated magadiites with a different amount of the attached silyl group were synthesized by the silylation of the dodecylammonium-exchanged magadiite with the tuned amount of 3-(mercaptopropyl)trimethoxysilane and the subsequent oxidation of the attached thiol to sulfonic acid. The arylsulfonated magadiite was synthesized by the silylation of the dodecylammonium-exchanged magadiite with 2-(4-chlorosulfonylphenyl)ethyltrimethoxysilane and the subsequent hydrolysis of the attached sulfonyl chloride to sulfonic acid. The X-ray diffraction (XRD) patterns and elemental mappings of the products, and the photoluminescent spectra of the Eu(3+)-exchanged products suggested that propylsulfonic or arylsulfonic acid was homogeneously distributed in the interlayer space. When all the sulfonated materials were used as an acid catalyst for condensation between phenol and acetone, p,p' bisphenol A selectively formed over the o,p' isomer, and higher yield and selectivity were attained on the catalysts with larger amount of the attached sulfonic acid. When the interlayer space of the propylsulfonated magadiite was expanded by the co-attachment of octadecylsilyl group, lower selectivity was obtained. The arylsulfonated magadiite showed considerably higher p,p' bisphenol A yield than the propylsulfonated magadiites.
