The present report describes the novel and smooth generation of sulfenate salts by fluoride-mediated cleavage of 2-(trimethylsilyl)ethyl sulfoxides. Efficiency of the process was elucidated through further reaction with alkyl halides to give stable sulfoxide end products.

A collection of aryl and alkyl 2-(trimethylsilyl)methyl sulfides have been converted to their respective sulfoxides by four different asymmetric oxidizing agents. The chemical yields range from 44–98% while the enantiomeric excesses range from 0–89%. The Davis oxazaziridine (3′S,2R)-(−)-N-(phenylsulfonyl)-(3,3-dichlorocamphoryl)oxaziridine was shown to be superior to the. Modified Sharpless Reagent

Stereoretentive Palladium-Catalyzed Arylation, Alkenylation, and Alkynylation of 1-Thiosugars and Thiols Using Aminobiphenyl Palladacycle Precatalyst at Room Temperature
A general and efficient protocol for the palladium‐catalyzed functionalization of mono‐ and polyglycosyl thiols by using the palladacycleprecatalyst G3‐XantPhos was developed. The CS bond‐forming reaction was achieved rapidly at roomtemperature with various functionalized (hetero)aryl‐, alkenyl‐, and alkynyl halides. The functional group tolerance on the electrophilic partner is typically high and
