22. 2 (0.02 mmol) and CuCl (0.10 mmol) were added. The reaction progress was monitored by GC. Analyses were made before adding the catalyst and every hour thereafter for the duration of the reaction. The extent of conversion of the substrates was calculated using the internal standard method
23. 2 (0.22 mmol) and CuCl (1.1 mmol) were added (at ambient temp or at 0°C) and the reaction was carried out for 2 h. The catalyst was removed via column chromatography and products were isolated by vacuum distillation (yields are included in Table 1)

27. 2 (200 mg, 0.24 mmol) in benzene (5 mL) and the reaction mixture was refluxed for 24 h. The solvent was evaporated under reduced pressure and 2 mL of cold hexane (-50°C) was added. The supernatant was removed and the yellow precipitate was washed twice with hexane (at -50°C) and dried in vacuo. Yield 15% (not optimized)
