NbCl5 as Catalyst in Diels-Alder Reaction of Furan Ring
Figure 1. Natural products deriving from 7-oxanorbonene. It is reported that uncatalyzed Diels-Alder reactions of furan take several weeks to give low yields due to diene’s low reactivity. The use ofExpand
Methyl Esters Production by Heterogeneous Catalyst Mixtures of CaO/Nb2O5 with Simulation of Analysis of Environmental Impacts
The conventional biodiesel process, although it reaches high conversion yields and productivity, faces problems related to the use of homogeneous catalysts. This work aims to study mixtures ofExpand
Synthesis of novel 4-amidopyranonaphthoquinone derived from nor-lapachol by Prins-Ritter reaction
The multi-component one-pot synthesis has received great importance because of its wide range of applications in pharmaceutical chemistry for the production of structural scaffolds and combinatorialExpand
Effect of Nb2O5·nH2O Termal Treatment on the Esterification of a Fatty Acid
In general, esterification reactions are favored by the increase in reaction temperature, excess of one of the reactants (usually alcohol), and additions of acid or basis catalysts. Esterification ofExpand
