Alcohols are among the most abundant building blocks in chemistry. Fluorinated compounds, meanwhile, are essential for many modern medicines, crop protection products and advanced materials. Converting one into the other, however, has traditionally relied on toxic, thermally unstable reagents such as DAST (diethylaminosulfur trifluoride) that make large-scale manufacturing operationally demanding.

Researchers are therefore seeking safer and more practical ways to carry out these fluorination reactions. One major goal is to use simple, inexpensive and widely available fluoride sources such as potassium fluoride in order to make the process safer, more scalable and more sustainable.
