A general and green fluoroalkylation reaction promoted via noncovalent interactions between acetone and fluoroalkyl iodides.

The first example of visible light promoted fluoroalkylation reactions initiated via noncovalent interactions between acetone and fluoroalkyl iodides is presented. The reaction system features synthetic simplicity, mild reaction conditions without any photoredox catalyst, and high functional group tolerance. A wide range of substrate scopes such as alkenes, alkynes and (hetero)arenes were all compatible with the reaction system.
