Simple and selective synthesis of fluoromethylated alkenes, heterocycles, enamines and heteroarenes by using the readily available and bench-stable fluoromethylphosphonium iodide salts is described. Key to this privileged transformation is the formation of a photoactive charge-transfer complex involving the σ-hole effect of phosphonium salts.
