Abstract

ALVES, Diego et al. Copper catalyzed cross-coupling reactions of diaryl ditellurides with potassium aryltrifluoroborate salts. J. Braz. Chem. Soc. [online]. 2009, vol.20, n.5, pp.988-992. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532009000500025.

Apresentamos aqui resultados das reações de acoplamento de diteluretos de diarila com sais de ariltrifluoroborato de potássio, usando quantidades catalíticas de Cu(OAc)2 e bipiridina, em uma mistura de DMSO/H2O, sob ar atmosférico. Estas reações de acoplamento são gerais e são realizadas com diteluretos de diarila e sais de ariltrifluoroborato de potássio contendo substituintes neutros, retiradores e doadores de elétrons, fornecendo os correspondentes teluretos de diarila não simétricos em rendimentos de bons a excelentes.

Keywords : tellurium; trifluoroborate salts; copper catalysis.
