Direct Photoactivation of Sulfinic Acids to Access Hydrosulfonylation and Arylsulfonylation of Alkenes.

Summary: Scientists have found a simple and clean way to make useful chemicals called sulfones. Normally, making these chemicals requires extra helper ingredients to make the reaction work. But this new method only uses a starting chemical called sulfinic acid and shines light on it. The light gives it the energy needed to react. This process is great because it doesn't need any extra chemicals, making it an easy and practical way to build new molecules for materials and medicines.
