(a) Photocatalytic vinylation of an N-aryl amine. Irradiation with a 415 nm LED (7.0 W output) with a 400 nm long pass filter, 100 mM phenyl trans-styryl sulfone, 2.5 equiv N-phenyl pyrrolidine (NPP), 3.0 equiv cesium acetate, 1 mol % catalyst in 2 mL of deaerated toluene/acetonitrile (3/1 v/v) in a Schlenk tube under nitrogen at up to 35 °C (temperature fluctuations caused the LED radiation). The yield was determined by isolating the product. (b) Plausible reaction mechanism similar to that postulated for an Ir^III-based photocatalyst.⁸²
