Xanthic anhydrides: A novel and convenient source of alkoxythiocarbonyl and alkyl radicals

Autor: J. E. Forbes, Samir Z. Zard

Publikováno v: Tetrahedron. 49:8257-8266

Upon irradiation with visible light, xanthic anhydrides 14 undergo a chain reaction leading to xanthates 17 and involving β-scission of the intermediate alkoxythiocarbonyl radical.

ChemInform Abstract: A New Radical-Based Synthesis of Lactams and Indolones from Dithiocarbonates (Xanthates)

Autor: Laurent Boiteau, Jean Boivin, J. E. Forbes, Samir Z. Zard, Jonathan Axon

Publikováno v: ChemInform. 25

N,N-disubstituted a-(xanthyl)-acetamides with an olefin on one of the substituents undergo cyclisation to a lactam by a radical chain reaction involving transfer of the xanthate group; anilides lead to the corresponding indolones.

Dithiocarbonate group transfer in radical chain reactions

Autor: C. Tailhan, Samir Z. Zard, J. E. Forbes

Publikováno v: Tetrahedron Letters. 31:2565-2568

Alkyl and cycloalkyl xanthates can serve as a convenient source of carbon centered radicals in a chain process involving carbon-carbon bond formation, and initiated by a suitable peroxide.
