YieldReaction ConditionsOperation in experiment
50% With potassium phosphate; tetrakis(triphenylphosphine) palladium(0); In water; toluene; at 60 - 110℃;Inert atmosphere; General procedure: Toluene wasdegassed by exchanging between vacuum and a stream ofargon (3 ×). 2,3,5,6-Tetrabromothieno[3,2-b]thiophene(1.0 equiv) and Pd(Ph3P)4 (0.05-0.10 equiv) were dissolvedin this degassed toluene (4 mL) at 60-70 C. To the obtainedsolution H2O (1 mL), K3PO4 (2.0 equiv), and arylboronicacid (1.2 equiv) were added. The reaction was vigorouslystirred under argon atmosphere at 110 C until TLC (100%hexane) showed the complete consumption of the startingmaterial. The reaction mixture was filtered to removeinsoluble particles. The filtrate was washed several timeswith H2O, dried over Na2SO4 and concentrated underreduced pressure by rotary evaporation. The residue waspurified by SiO2 column chromatography (100% hexane) togive the product as a white solid. In case of alkoxyphenylboronic acid, 1,4-dioxane was used instead of toluene (ref.6b). In fact, toluene-H2O gave the same result.
