Reaction Steps

2-dec-1-ynyl-3-decanyldithieno[2,3-d:2′,3′-d′]thieno[3,2-b:4,5-b′]dithiophene (107) (2.2 g, 4.15 mmol) is dissolved into ethyl acetate (30 mL) and to this solution, 5% Pt/C (0.5 g) is added. The mixture is stirred under a H2 atmosphere (90 psi) for 24 hours, then filtered. After removal of the ethyl acetate, the residue is purified by chromatography on silica gel eluted with hexane to produce the target compound (2.00, 90.5% yield). M.P.: 50.9-52.5° C. 1HNMR (CD2Cl2): δ 7.41 (d, 1H), 7.33 (d, 1H), 2.83 (t, 2H), 2.50 (t, 2H), 1.73-1.26 (m, 32H), 0.87 (m, 6H). 13CNMR: 140.85, 140.40, 139.93, 133.38, 133.14, 132.22, 129.69, 121.17, 120.09, 98.92, 32.29, 32.25, 29.99, 29.94, 29.72, 29.63, 29.52, 29.33, 29.18, 29.06, 28.94, 23.05, 14.23.
