    • General Procedure for the Cross-Coupling Reaction To a solution of appropriate 3-iodoselenophene (0.25 mmol) in DME (2.5 mL) was added Pd(OAc)2 (0.003g, 5 mol, and boronic acid (0.35 mmol) under argon. The resulting solution was stirred for 30 min at r.t. After this time, a solution of K3PO4 (1.2 mmol, 0.254 g) in H2O (0.6 mL) was added. The mixture was then heated at reflux during 1-15 h, cooled to r.t, diluted with CH2Cl2 (20 mL, and washed with brine (2 x 20 mL, The organic phase was separated, dried over MgSO4, and concentrated under vacuum. The residue was purified by flash chromatography on silica gel using hexane as eluent.
