A copper-catalyzed sulfoxidation of benzylic C-H bonds by nondirected oxidative C(sp3)-H activation was developed. The process proceeds via sulfenate anions, which are generated by base-triggered elimination of β-sulfinyl esters and benzyl radicals. The functional group tolerance is high, and the product yields are good.

A general and efficient protocol for the palladium-catalyzed functionalization of mono- and polyglycosyl thiols by using the palladacycle precatalyst G3-XantPhos was developed. The C-S bond-forming reaction was achieved rapidly at room temperature with various functionalized (hetero)aryl-, alkenyl-, and alkynyl halides. The functional group tolerance on the electrophilic partner is typically high and anomer selectivities of thioglycosides are high in all cases studied. New sulfur nucleophiles such as thiophenols, alkythiols, and thioaminoacids (cysteine) were also successfully coupled to lead to the most general and practical method yet reported for the functionalization of thiols.

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 sulfox
Asymmetric chemical oxidations of aryl and alkyl 2-(trimethylsilyl)ethyl sulfides
Schwan,Pippert
, p. 131 - 138 (2007/10/02)
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
