Procedure
-
To a degassed solution of diphenylacetylene (100 mg, 0.561 mmol) and bis(pinacolato)diboron (144 mg, 0.567 mmol) in DMF (0.5 mL) and toluene (0.5 mL) was added Pt(PPh3)4 (2 mg, 0.25 mol%). The reaction mixture was heated to 80 °C for 24 hours. After this time, the reaction was diluted with toluene (10 mL) and washed with saturated aqueous NH4Cl (2 x 10 mL). The organic phase was dried over MgSO4 and concentrated under reduced pressure. Recrystallization from MeOH afforded 1 as a white solid (241 mg, 0.558 mmol, 99%).
