Metathesis reactions have emerged in the last few decades as important tools for a wide variety of organic synthesis, combining high yields and sustainability. In spite of intense studies in this area and developments ...

Um dos mais intrigantes fatos semânticos da língua árabe é a metátese, transposição de fonemas dentro de uma palavra, frequentemente com relação de sentido entre as formas metatéticas. Em m-th-l, a raiz triconsonantal para ...

In this work new methodologies with technological potential for high value-added products were developed from biorenewable 1-propenylbenzenes, anethole, isoeugenol and isosafrol, available in abundance in Brazil. This ...

In this work, a study of different synthetic ways was made in order to obtain spiro compounds starting from R-(-)-carvone, getting to the formation of cycloheptenone as an intermediate, which undergoes two consecutives ...

In this work, the reactions of cross-metathesis of substrates of natural origin (anethole, isoeugenol and isosafrole) were studied with the following acrylates: methyl acrylate, ethyl acrylate and 2-ethylhexyl acrylate in ...

In this work the cross-metathesis reactions of substrates of natural sources (estragole, methyl eugenol, safrole and eugenol) with methyl acrylate using dichloroethane and dimethyl carbonate as solvent were studied employing ...
