2-Phenylselenyl-3,3-diarylcyclobutene (6), typical procedure: Under an N2 atmosphere, a solution of diphenylmethylenecyclopropane (1a, 0.062 g, 0.3 mmol), diphenyl diselenide (0.094 g, 0.3 mmol) and Cu(OAc)2 (0.060 g, 0.3 mmol) in AcOH (2 mL) was irradiated with a tungsten lamp (300 W). The temperature rose to 40 °C because of the irradiation. The reaction was monitored by TLC (PE). When the reaction was complete, the solvent was evaporated under vacuum and the residue was subjected to preparative TLC (PE) to afford 6a in 65% yield. IR (KBr): 3055, 1575, 1491, 1217, 1025, 750, 696 cm-1; 1H NMR (400 MHz, CDCl3): δ = 7.22-7.60 (m, 15 H), 6.12 (t, J = 0.8 Hz, 1 H), 3.17 (d, J = 0.8 Hz, 2 H); 13C NMR (100 MHz, CDCl3): δ = 46.9, 61.9, 126.4, 127.4, 127.5, 128.0, 128.1, 129.3, 133.9, 134.8, 141.8, 144.1; MS (EI, 70 eV): m/z (%) = 362 (12) [M+], 281 (14), 205 (100); HRMS (EI): m/z calcd for C22H18Se: 362.0574; found: 362.0574.

1,1-Diaryl-2-phenylselenylbuta-1,3-diene (11), typical procedure: Under an N2 atmosphere, a solution of diphenylmethylenecyclopropane (1a, 0.062 g, 0.3 mmol), diphenyl diselenide (0.094 g, 0.3 mmol) and Cu(OAc)2 (0.060 g, 0.3 mmol) in AcOH (0.2 mL) acid was stirred at 110 °C. The reaction was monitored by TLC (PE). When the reaction was complete, the solvent was evaporated under vacuum and the residue was subjected to preparative TLC (PE) to afford 11a in 68% yield. IR (film): 3054, 1576, 1477, 1440, 737, 697 cm-1; 1H NMR (400 MHz, CDCl3): δ = 7.14-7.34 (m, 15 H), 6.56-6.63 (m, 1 H), 5.81-5.85 (m, 1 H), 5.22-5.25 (m, 1 H); 13C NMR (100 MHz, CDCl3): δ = 120.9, 125.8, 127.3, 127.7, 128.1, 128.9, 129.4, 130.0, 130.1, 130.2, 133.0, 135.4, 141.6, 144.1, 151.6; MS (EI, 70 eV): m/z (%) = 362 (30) [M+], 281 (15), 205 (100); HRMS (EI): m/z calcd for C22H18Se: 362.0574; found: 362.0567.
