What is it about?
The scientific publication describes a study on how to improve the enantioselectivity in chiral catalysis, specifically in enantioselective hydrogenation reactions. The researchers immobilized chiral organometallic complexes in supported ionic liquids for realizing the reaction. The results showed that this combination led to higher enantioselectivity in the hydrogenation of acetophenone, which was chosen as test reaction for the enantioselective reduction of prochiral ketones. The study also provides insight into the mechanisms of the reaction and suggests that the unique solvent properties of ionic liquids induced the formation of solvent cages of ionic liquid molecules around the chiral complexes. Overall, the research contributes to improving the efficiency and effectiveness of enantioselective chemical transformations, which has important implications in the production of pharmaceuticals and in the chemical industry.

Why is it important?
The work presented in this scientific publication is important because it contributes to the development of more efficient and effective enantioselective chemical transformations. Enantioselective reactions are important in the production of pharmaceuticals and other chemicals because they enable the production of specific molecules with a desired stereochemistry, which is often necessary for the effectiveness and safety of these compounds. Nevertheless, achieving high selectivity in these reactions can be challenging. The use of supported ionic liquids as a solvent and the immobilization of chiral organometallic complexes have been found to increase the enantioselectivity of the reaction, providing new insights into the mechanisms of the reaction and suggesting new avenues for the development of chiral catalysts. Ultimately, this research could lead to the development of more efficient and cost-effective processes for the production of pharmaceuticals and other chemicals, benefiting various industries and improving the quality of life for people around the world.
