Participants

Reaction Steps

Compound 2 was synthesized as shown in Scheme 2. Under acid condition, dithieno[3,2-b:2′,3′-d]thiophene (Organic Syntheses, Vol. 83, p. 209 (2006)) was reacted with NBS affording 2-bromodithieno[3,2-b:2′,3′-d]thiophene 7, which underwent Suzuki cross-coupling reaction with boronic acid R1—B(OH)2 (J. Mater. Chem., 2010, 20, 2182-2189) to afford intermediate 8 in 71% yields. Finally 8 was converted to PhN-OFFT-TCN by reacting with n-BuLi and tetracyanoethylene at low temperature in 85% yield.
