    • General Procedure: A mixture of diaryl diselenide (0.5 mmol) and zinc powder (3.0 mmol) in anhydrous MeCN (15 mL, was stirred at 70°C. After 15 min, anhydrous AlCl3 (3.0 mmol in 2 mL anhydrous MeCN) was added cautiously. The mixture was stirred for 1 h at 70 °C, until the yellow solution turned colorless. The mono-activated cyclopropane (1.1 mmol) was then added to the solution and the mixture was stirred at 70 °C for the period of time specified in Table 1. The progress of reaction was monitored with TLC. After the reaction was complete, the solution was filtered and the solvent was evaporated. Aqueous HCl (10, was added to the crude product and the mixture was extracted with EtOAc (2 × 30 mL, The combined organic layers were dried over anhydrous Na2SO4, filtered, and the solvent was removed under reduced pressure. Purification by preparative TLC (silica gel; n-hexane-EtOAc, 3:1) gave the corresponding arylselenenyl-f
