The Synthesis of Octyl-Substituted Hexathia[7]heterohelicene Based on dithieno[2,3-b:3,2-d]thiophene via Irradiation
摘要:
With 2-octyl dithieno[2,3-b:3',2'-d] thiophene as raw material, three steps including formylation, McMurry reaction and photocylization were employed to generate dioctyl-hexathia[7] heterohelicene in total yield of 29.9%. The crystal analysis shows that some short intermolecular interactions including S. S and C. S interactions were observed in the crystal of target compound.
