14187-32-7. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 14187-32-7, Name is Dibenzo-18-crown-6. In a document type is Article, introducing its new discovery.
Stereoselective hydrogenation of dibenzo-18-crown-6 catalyzed by carbon nanotube-supported rhodium nanoparticles
Multiwalled carbon nanotube-supported Rh nanoparticles prepared by a simple sonochemical method are highly active for catalytic hydrogenation of dibenzo-18-crown-6 to dicyclohexyl-18-crown-6. The catalytic hydrogenation reaction shows a selectivity favoring the cis-syn-cis isomer over cis-anti-cis isomer of the product by a factor of ?6. Conventional Rh catalysts supported by activated wood carbon, SiO2, or Al2O3 can only convert dibenzo-18-crown-6 to dicyclohexyl-18-crown-6 with an cis-syn-cis=cis-anti-cis ratio of <1.7. The Rh nanoparticle catalyst can be reused at least six times without losing its catalytic activity. Taylor & Francis Group, LLC. 14187-32-7, I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 14187-32-7, help many people in the next few years.
