All measurements were made in duterated chloroform and dimethyl sulfoxide
Thus, new methods for obtaining optically active sulfoxides
are required for the synthesis of enantiomerically enriched compounds.
Hence, an attempt has been made to prepare cyanate esters with sulfoxide
linkage, which imparts flexibility to the polycyanurates.
Removal of sulfones and sulfoxides
, created during oxidation, was carried out by extraction followed by adsorption with silica gel to reach sulfur content levels of 7.
2,3) The enzyme responsible for the S-oxidation of SCMC to SCMC sulfoxide
has been reported to be phenylalanine hydroxylase.
(11) and other sulfoxides
(12), formamide (13), nonionic detergents (14), and compounds belonging to the family of compatible solutes, such as betaine (15-17).
Instituto Mexicano del Petroleo (Mexico) and Universidad Nacional Autonoma de Mexico (Mexico) have patented a method of removing thiophenic and organosulfide compounds from a fossil fuel comprising the steps of contacting the fossil fuel with hemoproteins, which oxidize the sulfur containing compounds to sulfoxides
and sulfones in a reaction system containing organic solvent or not, and followed by a distillation step in which sulfoxides
and sulfones are removed from the fuel.
Onions mainly contain S-propenylcysteine sulfoxide
(1), but also other sulfoxides
, including S-propylcysteine sulfoxide
and S-methylcysteine sulfoxide
Recent studies in Rayner's group have involved the oxidation of organic sulfides to sulfoxides
using a hydroperoxide catalyst in conjunction with a sulfonium ion exchange resin.
