Procedure
100 mg (0.431 mmol) of tri(2-furyl)phosphine oxide (31P NMR, s, −15.4) were treated with I2 11 mg (43 μmol) and tributylphosphine 180 μL (0.70 mmol) in acetonitrile/THF (1:1 v/v) 2 mL for 19 hours at room temperature, which gave 31P NMR integrated conversion of tri(2-furyl)phosphine (31P NMR, s, −76.5) in ca. 50%.
