An ambient‐light‐promoted, metal‐free strategy for the direct perfluoroalkylative cyclization of β,γ‐unsaturated hydrazones is reported. This radical process has wide functional‐group tolerance, is performed under mild reaction conditions, and is operationally simple. The perfluoroalkylated pyrazoline products are obtained in good to excellent yields. TMG = 1,1,3,3‐tetramethylguanidine.
