Paragraph 0067-0069, (2021/02/13)
To provide an ionic liquid or the like which is excellent in thermal stability, solubility in a fluorine-based solvent, and fluidity, has a high bonding ratio, and is capable of forming a thin monomolecular film.SOLUTION: The ionic liquid comprises a cati
Rapid transformation of sulfinate salts into sulfonates promoted by a hypervalent iodine(III) reagent

An alternative method for forming sulfonates through hypervalent iodine(III) reagent-mediated oxidation of sodium sulfinates has been developed. This transformation involves trapping reactive sulfonium species using alcohols. With additional optimization of the reaction conditions, the method appears extendable to other nucleophiles such as electron-rich aromatic systems or cyclic ethers through a ring opening pathway.

Page/Page column 6, (2010/12/18)
A process of preparing a radioactive compound containing a fluorine-18 isotope is provided. In one embodiment, the process may comprise forming a [18F] fluoroalkyl triflate by triflating a [18F] fluoroalkyl compound with AgOTf, and f
Stereocontrolled synthesis of novel enantiomerically pure sulfides and selenides from (+)-camphor and (+)-camphor-10-sulfonyl chloride

Synthetic approaches to novel enantiomerically pure sulfides and selenides derived from (+)-camphor and (+)-camphor-10-sulfonate esters are described. Lewis acid mediated hemiacetal formation between a camphor- derived ketone and a thiol or selenol, and subsequent in situ reduction using triethylsilane selectively gives the exo-sulfide or -selenide in moderate overall yields. The initial sulfonate ester products can be converted into the corresponding sulfones by subsequent treatment with Grignard or organolithium reagents.
