How do you make Sulfoxides?
An oxidative variant of the thiol-ene reaction enables the direct addition of thiols to olefins to form sulfoxides in the presence of tert-butyl hydroperoxide as oxidant and methanesulfonic acid as catalyst. The latter is believed to catalyze the oxidation of the intermediate sulfide to the sulfoxide.
Why is sulfoxide chiral?
Sulfur is well-suited to the role of an agent for transfer of chirality for several reasons. The faces of a sulfoxide are highly differentiated due to the large steric difference between its substituents, which range from an electron lone pair to large alkyl groups like tert-butyl.

Is sulfide a functional group?
An organic sulfide (British English sulphide) or thioether is a functional group in organosulfur chemistry with the connectivity C–S–C as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors.
How do you make sulfone?
Synthesis of sulfones. Oxidation of sulfides with 30% hydrogen peroxide catalyzed by tantalum carbide provides the corresponding sulfoxides in high yields, whereas niobium carbide as catalyst efficiently affords the corresponding sulfones. Both catalysts can easily be recovered and reused without losing their activity.

What is a sulfide group?
sulfide mineral, sulfide also spelled sulphide, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic lustre and electrical conductivity.

Is sulfone an antibiotic?
Sulfone antibiotics are used for infectious diseases (eg, leprosy); however, sulfones are effective in inflammatory diseases.
What is a sulfone drug?
The sulfones, which are bacteriostatic, are used principally for the treatment of leprosy. They are useful for the treatment of a variety of dermatologic disorders, such as dermatitis herpetiformis. Effectiveness in this condition may be due primarily to its anti-inflammatory, rather than antibacterial, effect.
Can humans use DMSO?
Background: Dimethyl sulfoxide (DMSO) has been used for medical treatment and as a pharmacological agent in humans since the 1960s. Today, DMSO is used mostly for cryopreservation of stem cells, treatment of interstitial cystitis, and as a penetrating vehicle for various drugs.
Can I take DMSO orally?
DMSO is a prescription medicine and dietary supplement. It can be taken by mouth, applied to the skin (used topically), or injected into the veins (used intravenously or by IV).
What is the COO functional group?
One example of a strongly hydrophilic group is the carboxyl group (COOH), which can act as an acid and lose a proton to form a negatively-charged carboxylate ion (COO −start superscript, minus, end superscript). Carboxyl groups are commonly found in amino acids, fatty acids, and other biomolecules.
What is the prefix of COO?
