“Dyes, pharmaceuticals, and functional materials – all of these products are generally based on innovative molecules made by chemists. For their production several chemical reactions are available to the expert, however, limitations remain. For example, fluorinated compounds, molecules that contain at least one fluorine atom, are often rather difficult to prepare. This is unfortunate, since they exhibit interesting chemical properties and are of greatest importance for the development of active ingredients. Thus, new ways have to be found to produce these compounds. Now, chemists from the Westfälische Wilhems-Universität (WWU) made the impossible possible: they have developed a new and practical synthetic method for the formation of such fluorinated three-dimensional “saturated” (meaning only single-bond containing) molecular ring structures. The report of Prof. Dr. Frank Glorius, Mario Wiesenfeldt, Dr. Zackaria Nairoukh and Dr. Wei Li has just been published online in the learned journal “Science“.”
