Gif-type oxidation systems. Evidence for a second intermediate between saturated hydrocarbon and ketone
Barton,Csuhai,Ozbalik
, p. 2717 - 2820 (1990)
The addition of dianisyl telluride to a Gif(IV) oxidation of adamantane has a marked effect on the ratio of ketone to secondary alcohol formed. This is interpreted as an indication of a second intermediate in the conversion of saturated hydrocarbvons into ketones. This second intermediate is probably an Fe(III) alkoxide.
The highly selective metal-free oxidation of sulfides, tellurides and phosphines using sodium bromate in the presence of recyclable ionic liquid [bmim]HSO4, at 80°C
Rajeswari,Lumb, Anshika,Khurana, Jitender M.
, p. 442 - 444 (2016/07/21)
The metal-free oxidation of sulfides to sulfones using sodium bromate (NaBrO3) in [bmim]HSO4:H2O (3:1, v/v) at 80°C is reported. Phenylalkyl, phenylbenzyl, diaryl and heteroaryl sulfides were transformed to the corresponding sulfones. Aryl tellurides and phosphines were oxidised to the corresponding telluroxides and phosphine oxides. All the reactions proceeded smoothly and gave high yields in 20-55 min. The ionic liquid [bmim]HSO4 was easily recovered and recycled.
Aqueous sodium hypochlorite mediated chemoselective oxidation of chalcogenides to monoxides and dioxides by microwave exposure
Khurana, Jitender,Nand, Bhaskara
experimental part, p. 906 - 909 (2011/01/08)
A solvent-free, rapid, and highly selective oxidation of sulfides, selenides, and tellurides (chalcogenides) to the corresponding monoxides (sulfoxides, selenoxides, and telluroxides) or the corresponding dioxides (sulfones, selenones, and tellurones) has been developed using aqueous sodium hypochlorite on solid supports by exposure to microwave. Chemoselectivity and quantitative yields have been attained in most cases.
