Comparison of Ullmann/RCM and Ullmann/Bis-hydrazone Coupling Reactions; New Access to Benzodithiophenes for Dye-Sensitized Solar Cell and Thiahelicene Applications / G.R. Stephenson, S. Cauteruccio, J. Doulcet. - In: SYNLETT. - ISSN 0936-5214. - 25:5(2014), pp. 701-707. [10.1055/s-0033-1340667]
Abstract:
The use of CuTC (Liebeskind’s catalyst), followed by methylenation and ring-closing metathesis, or bis-hydrazone coupling reactions is described. This approach establishes an alternative non-photochemical synthesis of the strategically important 1,2-b:4,3-b′ BDT regioisomer, which has previously been underused in applications such as dye-sensitized solar cells and nonlinear optics because of the difficulty of synthesis on a large scale
