Brønsted acid-catalyzed synthesis of sulfinamidines and sulfinimidate esters through electrophilic fluorination and substitution.

Summary: Scientists have found a new, easy way to build specific sulfur molecules that are very useful for making medicines. Instead of using harsh metals, they use a simple acid and a fluorine chemical to help attach new parts to the sulfur. This process works at room temperature, gives great results (up to 97% success), and can be done on a large scale. It is a powerful new tool for creating and improving drugs!
