YieldReaction ConditionsOperation in experiment
6.3% With toluene-4-sulfonic acid; In toluene; at 90℃; for 96h;Inert atmosphere; e) In an oven-dried round bottle flaskfilled with argon <strong>[51792-34-8]3,4-dimethoxythiophene</strong> (2.0 g, 13.9 mmol) and diol 7 (1.19 g, 13.8 mmol)were dissolved in toluene (60 mL). To the mixture was added pTSA (0.26 g, 1.39 mmol) andthe solution was heated at 90 °C for 1 day. A second portion of diol 7 (1.19 g, 13.8 mmol)was added to the warm mixture which was kept stirring at 90 °C for another three days. Theresulting solution was filtered through a pad of celite and concentrated under vacuum. Thecrude product appeared as green-black oil. It was purified by flash column chromatography(SiO2; petroleum ether/dichloromethane, 4:1) to yield the ethynyl-(EDOT) (eEDOT) 8 ascolorless oil (0.145 g, 6.3 percent). 1H NMR (499.93 MHz, CDCl3, 25°C): delta = 6.41 (d, J = 3.8 Hz,1H, H-1/4), 6.37 (d, J = 3.8 Hz, 1H, H-1/4), 4.90 (dt, J = 6.6, 2.3 Hz, 1H, H-7), 4.27 (dd, J =11.6, 2.3 Hz, 1H, H-8), 4.13 (dd, J = 11.6, 6.6 Hz, 1H, H-8?), 2.61 (d, J = 2.3 Hz, 1H, H-11).13C NMR (75.4 MHz, CDCl3, 25 °C): delta = 140.8 (C-2/3), 140.4 (C-2/3), 101.0 (C-1/4), 100.4(C-1/4), 77.3 (C-10), 76.5 (C-7), 67.6 (C-8), 64.3 (C-11). IR (neat, /cm-1): 3264, 2963, 1482,1258, 1011, 788. HRMS, calculated for C8H7O2S: m/z = 167.01613, found: m/z = 167.01602([M + H+]).
