Clay-supported tetrabutylammonium periodate as a versatile oxidant for alcohols and sulfides
Venkatachalapathy,Rajarajan,Shayira Banu,Pitchumani
, p. 4071 - 4076 (1999)
Clay-supported tetrabutylammonium periodate is found to oxidise efficiently benzylic alcohols to the corresponding aldehydes without overoxidation to acids. It also oxidises aryl sulfides selectively to the corresponding sulfoxides.
Aerobic oxidation of sulfides with a vitamin B2-derived organocatalyst

, p. 1679 - 1682 (2013)
5-Ethyl-3-methyl-2′,4′:3′,5′-di-O-methylenedioxy- riboflavinium perchlorate (DMRFlEt+ClO4-) is readily derived from commercially available vitamin B2 (riboflavin) and exhibits high catalytic activity for the oxidation of organic sulfides under an oxygen atmosphere (1 atm) with the assistance of hydrazine hydrate as a reductant. This is an inexpensive, convenient, and environmentally benign method for the selective oxidative transformation of sulfides into sulfoxides. Georg Thieme Verlag Stuttgart New York.
Selective and efficient oxidation of sulfides to sulfoxides with N-bromosuccinimide in the presence of β-cyclodextrin in water
Surendra,Krishnaveni, N. Srilakshmi,Kumar, V. Pavan,Sridhar,Rao, K. Rama
, p. 4581 - 4583 (2005)
A simple and highly selective oxidation of sulfides to sulfoxides with N-bromosuccinimide (NBS) catalyzed by β-cyclodextrin in water has been developed. A series of sulfides were oxidized selectively at room temperature in excellent yields. This reaction

Srinivasan, Chockalingam,Kuthalingam, Packiam,Arumugam, Nateson
, p. 170 - 175 (1980)
The kinetics of oxidation of alkyl aryl sulphides by peroxodiphosphate ion were investigated in 50percent (v/v) aqueous acetic acid.At constant and ionic strength, the reaction is second-order, first order in sulphide and in peroxodiphosphate.An an
pH-dependence of the aqueous phase room temperature Br?nsted acid-catalyzed chemoselective oxidation of sulfides with H2O2
Shen, Hai-Min,Zhou, Wen-Jie,Ma, Xin,Wu, Hong-Ke,Yu, Wu-Bin,Ai, Ning,Ji, Hong-Bing,Shi, Hong-Xin,She, Yuan-Bin
, p. 16709 - 16722 (2015)
A pH-dependence of the Br?nsted acid-catalyzed oxidation of sulfides to the corresponding sulfoxides with H2O2 is reported for the first time based on our systematic investigation of the catalytic performance of a series of Br?nsted acids. For all of the Br?nsted acids investigated, the catalytic performances do not depend on the catalyst loading (mol ratio of Br?nsted acid to substrate), but rather depend on the pH value of the aqueous reaction solution. All of them can give more than 98% conversion and selectivity in their aqueous solution at pH 1.30, no matter how much the catalyst loading is and what the Br?nsted acid is. This pH-dependence principle is a very novel perspective to understand the Br?nsted-acid catalysis system compared with our common understanding of the subject.
Enantioseparation of Sulfoxides and Nitriles by Inclusion Crystallization with Chiral Organic Salts Based on l-Phenylalanine
Kodama, Koichi,Kanai, Hayato,Shimomura, Yuki,Hirose, Takuji
, p. 1726 - 1729 (2018)
Enantioselective inclusion of aromatic sulfoxides and nitriles was achieved in a host framework created by organic salts comprising achiral benzoic acids and a chiral primary amine (1a) derived from l-phenylalanine. Tuning of the combined achiral acid component successfully changed the chiral recognition ability of the organic salts. The guest molecules were hydrogen-bonded to form three-component inclusion crystals, and the enantiomers of nitriles and sulfoxides were separated with high selectivity up to 92 and 98 % ee. As far as we know, this is the first example of the enantioseparation of non-functionalized aromatic nitriles.
Mechanism of the Oxidation of Alkyl Aryl Sulfides by Phenyliodoso Diacetate
Srinivasan, Chockalingam,Chellamani, Arunachalam,Kuthalingam, Packiam
, p. 428 - 431 (1982)
The rates of oxidation of 16 alkyl aryl sulfides by phenyliodoso diacetate have been studied in acetonitrile-water mixtures.Those sulfides containing electron-donating groups in the benzene ring accelerate the rate while those with electron-withdrawing gr
Kinetics and correlation analysis of reactivity in the oxidation of some alkyl phenyl sulfides by benzimidazolium dichromate
Pandey, Dinesh,Kothari, Seema
, p. 1224 - 1230 (2014)
The oxidation of some alkyl phenyl sulfides by benzimidazolium dichromate (BIDC) in dimethyl sulfoxide, to the corresponding sulfoxides, is first order with respect to BIDC. Michaelis-Menten type kinetics was observed with respect to sulfide. Thermodynami
Flavin-catalyzed generation of diimide: An environmentally friendly method for the aerobic hydrogenation of olefins
Imada, Yasushi,Iida, Hiroki,Naota, Takeshi
, p. 14544 - 14545 (2005)
The first green and practical method for "aerobic hydrogenation" involving the use of hydrazine and an organocatalyst is described. Olefins can be hydrogenated by treatment with hydrazine in the presence of a 5-ethyl-3-methyllumiflavinium perchlorate (FlEt+·ClO4-) catalyst under O2 atmosphere to give the corresponding hydrogenated products in excellent yields along with environmentally benign water and molecular nitrogen as the only waste products.

Dioxirane generated in situ by reaction of chiral 1,2:4,5-di-O- isopropylidene-D-erythro-hexo-2,4-diulo-2,6-pyranose with Oxone oxidizes prochiral sulfides to the corresponding sulfoxides with an enantiomeric excess of 2 to 25%. Pleiades Publishing, Inc., 2006.
