January 2022 - 107 articles

Cover Story: The chemical industry is becoming more and more environmentally conscious. Among the adopted measures are continuous flow processes or the replacement of noble by transition metals as catalysts. Under these premises, this article describes for the first time the use of Co in the chemoselective continuous flow hydrogenation of 2-methyl-2-pentenal. Our results reveal the influence of the loading on the generated particle size and surface characteristics modifying selectivity toward the hydrogenation of C=C or C=O bonds. In this way, the production of 2-methylpentanal (meprobamate drug precursor) or 2-methyl-2-pentenol (perfumes ingredient) can be tuned. Indeed, in this article, we show the optimal conditions to achieve almost 100% selectivity in the production of 2-methylpentanal. View this paper
