General procedure for homo-coupling reactions in Table 3
The substrate (0.54 mmol) in THF or diethyl ether was added
to a stirred solution of catalyst 4 (6 mg, 0.0108 mmol) in 3 mL
THF. The mixture was stirred at room temperature for
30 minutes and then 1 mL wet CHCl3 was added. The solution
was filtered through silica gel and the resulting mixture was
evaporated to dryness. The products were then separated by
column chromatography on silica gel (250–400 mesh) with
either pentane or pentane–diethyl ether (50 : 1) as the eluent.
The homo-coupling products were identified by comparison of
