Procedimiento

A dry 250 mL 1-neck flask was flushed with N2 and was charged with 4,8-bis(3-ethylhept-1-ynyl)thieno[2,3-f]benzothiophene (3.04 g, 0.007 mol), Pd/C wet support (0.82 g, 10%) and THF (15 mL, 0.5 M). The flask was evacuated and backfilled with hydrogen. The flask was kept under a hydrogen atmosphere and was monitored by TLC. After the reaction was completed, the mixture was filtered through Celite and solvent was removed by rotary evaporation. The solid was dissolved in hexanes and purified by column chromatography to yield oil (1.66 g, 54%).
