Benzo[b]benzo[4,5]thieno[3,2-d]thiophen-2-yl trifluoromethanesulfonate (1.5 g, 3.86 mmol), Pd2(dba)3 (0.071 g, 0.077 mmol), dicyclohexyl(2′,6′-dimethoxy-[1,1′-biphenyl]-2-yl)phosphine (0.127 g, 0.309 mmol), 4,4,5,5-tetramethyl-2-(3-(triphenylen-2-yl)phenyl)-1,3,2-dioxaborolane (1.82 g, 4.25 mmol), K3PO4 (2.46 g, 11.59 mmol), toluene (90 mL) and water (10 mL) were charged in a 250 mL flask. This mixture was bubbling with nitrogen for 30 minutes then heated up to reflux for overnight. After purification, 1.7 g (81%) of a white solid was obtained. The compound was confirmed by NMR.
