Scope of isomerizing alkenes over one carbon.^[a]

[a] Unless otherwise noted, all the reactions were carried out with alkenes (0.2 mmol), Co(acac)₂ (0.01 mmol), DPEphos (0.02 mmol), HEH (0.2 mmol), and K₂CO₃ (0.2 mmol) in anhydrous DMF (2 mL), irradiation with blue LEDs at 25 °C for 16 hours. [b] Yields of isolated products. [c] The ratio of E/Z was determined by ¹H NMR. [d] The reaction was carried out for 10 hours. [e] GC‐FID yields using 1,3,5‐trimethoxybenzene as an internal standard. [f] DPEphos was replaced by 4CzIPN (0.002 mmol) and Xantphos (0.02 mmol), irradiating for 24 hours. [g] 0.005 mmol of Co(acac)₂ was used and DPEphos was replaced by 4CzIPN (0.002 mmol), irradiating for 24 hours.
