Sulfoxide-mediated Umpolung of alkali halide salts

Autor: Christophe Farès, Sebastian Klimczyk, Xueliang Huang, Nuno Maulide

Publikováno v: Organicbiomolecular chemistry. 10(22)

A new protocol for the direct two-electron oxidative Umpolung of alkali halide salts is reported. This procedure, relying on the use of a commercially available sulfoxide as the oxidant, allows the electrophilic halogenation of carbonyl compounds as

Stereoselective intramolecular cyclopropanation through catalytic olefin activation

Autor: Luis F. Veiros, Sebastian Klimczyk, Nuno Maulide, Xueliang Huang

Publikováno v: Chemical Science. 4:1105

A novel stereoselective and convergent catalytic method for the cyclopropanation of electron-neutral and -rich olefins by sulfonium ylides is reported which unusually proceeds through olefin activation rather than by metal carbene formation.
