Building blocks for the future: Rhodium-catalyzed [2+2+1] cycloaddition achieves high enantioselectivity Cycloaddition reactions are an efficient strategy for constructing cyclic compounds that are important building blocks for other chemicals. In these processes, π-electrons from different unsaturated molecules, such as alkenes, alkynes, or dienes accommodate to form new cyclic structures in a single step. π-electrons are those responsible for the π-bonds in double and triple bonds. In a double bond, one of the C-C bonds is a π-bond, while in a triple bond, two of the C-C bonds are π-bonds.

Raman spectroscopy offers new insights into ionic liquid acidity Researchers at the University of Liège have for the first time determined the acidity of ionic liquids using Raman spectroscopy, thanks to Hammett acidity functions. This advance promises to revolutionize our understanding and use of these organic solvents, in which dissolved acids can be remarkably more acidic than in water, with an acidity that can be up to 100 million times greater.
