Abstract

VALE, Juliana A. et al. Lanthanide nitrates as Lewis acids in the one-pot synthesis of 1,2,4-oxadiazole derivatives. J. Braz. Chem. Soc. [online]. 2012, vol.23, n.8, pp.1437-1440.  Epub July 31, 2012. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532012005000002.

Neste trabalho relatamos o uso de nitratos de lantanídeos [Ln(NO3)3] atuando como catalisador na síntese de uma única etapa de derivados de 3-benzoíla- e 3-acetila-1,2,4-oxadiazóis a partir de cetonas, nitrilas e ácido nítrico. Este é o primeiro exemplo da síntese em única etapa de preparação de derivados benzoíla e acetila-1,2,4-oxadiazóis, usando acetofenonas com grupos doadores de elétrons.

Keywords : lanthanide nitrates; Lewis acids; 1,2,4-oxadiazole derivates.
