Light-Driven Chemistry: A New Way to Make Useful Molecules

Scientists have found a clever way to make special molecules using light. They used a simple method that doesn't need metals or strong chemicals. Instead, they used a special compound called trifluoromethyl thianthrenium triflate, or TT-CF3+OTf-, which is easy to make and stable in air. This method is special because it uses visible light to trigger a reaction. The light helps to add a trifluoromethyl group (CF3) to other molecules. At the same time, it also helps to form rings in these molecules. The result is a new type of molecule called trifluoromethylated dioxodibenzothiazepines, which could be useful in medicine. One of the best things about this method is that it's gentle. It doesn't need harsh conditions or expensive catalysts. This makes it a green and efficient way to create useful molecules. The molecules made in this way have a seven-membered ring with a nitrogen atom, which is a common feature in many medicines. The reaction happens at room temperature and doesn't need any special equipment. This makes it easy to do in any lab. The scientists also showed that this method can be used to make a variety of different molecules, which could be useful in many different fields. This new method is a big step forward in the field of chemistry. It shows that light can be used to drive reactions in a gentle and efficient way. This could lead to new discoveries and innovations in the future.
