Líquidos iônicos: aplicação na síntese de β-dimetilaminovinil cetonas e na N-alquilação de pirazóis
(Universidade Federal de Santa Maria, 2007-02-15)
The synthesis of two 1-methyl-3-alkylimidazolium tetrafluoroborate (where alkyl = butyl, octyl; [BMIM]BF4 and [OMIM]BF4) based on room temperature ionic
liquids (RTIL) is reported. The usefulness of these ionic liquids ...
Síntese e investigação da atividade biológica de pirazóis funcionalizados
(Universidade Federal de Santa Maria, 2006-08-16)
In this work, a method for the synthesis of a series of heterocyclic compounds that preserve the amino group of the starting material, is presented. For this study, a-oxoketene O,N-acetals were obtained from the reaction ...
