Phosphine/Sulfoxide-Supported Carbon(0) Complex

A new carbon(0) complex 2 with two different L ligands, a phosphine and a sulfoxide, was synthesized and fully characterized. This new type of carbone exhibits excellent coordination ability, in contrast to the related phosphine/sulfide-supported carbon(0

Reactivity in Methyl Transfer Reactions. 5. Relation between Rates and Equilibria

The methyl transfer reactions of two dimethylarylsulfonium ions with methyl phenyl sulfide are equilibrated in sulfolane solutions, as is the methyl transfer from methyldiphenylsulfonium ion to methyl 3,4-dichlorophenyl sulfide, and from dimethyl sulfate

Sonogashira reaction using arylsulfonium salts as cross-coupling partners

Triarylsulfonium, alkyl- and fluoroalkyl(diaryl)-sulfonium, and aryl(dialkyl)sulfonium triflates are successfully used as a new family of cross-coupling participants in the Sonogashira reaction as aryldiazonium, diaryliodonium, and tetraphenylphosphonium salts. It was found that terminal alkynes reacted mildly with triarylsulfonium or (2,2,2-trifluoroethyl)diphenylsulfonium triflate at room temperature under Pdand Cu-cocatalysis to give the corresponding arylalkynes in up to >99% yield. This protocol represents the first use of arylsulfonium salts as cross-coupling partners in the Pd/Cu-catalyzed Sonogashira reaction.

Synthesis and chemistry of enantiomerically pure 10,11-dihydrodibenzo[b,f] thiepines

Several chiral thiepines were efficiently constructed using sulfur diimidazole in combination with a variety of bislithiated carbon fragments. The sulfur atom in these thiepines is found to be unusually unreactive compared to diphenylsulfide. The Royal Society of Chemistry 2006.
