An efficient one-pot synthesis of functionalized trisubstituted thiophenes via the reaction of 3-morpholino-3-thioxopropanenitrile, cyclohexyl isocyanide and α-haloketones is reported. This method provides a straightforward route to a variety of highly substituted thiophenes not easily accessible by conventional methods.

Twist and shout: The synthesis of polyfunctional thiophenes is reported. Quantum-mechanical calculations explain the synthetic pathway of this heterocyclization. Both experimental and computational spectral results demonstrate that the optical properties of the synthesized thiophenes are caused by the presence of an intramolecular charge-transfer (ICT) state during absorption and a twisted ICT state

on the terminal aromatic ring or replacing this fragment with pyridine or pyrazine moieties resulted in increased quantum yields. To gain insight into the electronic structures and optical properties, quantummechanicalcalculations were performed. The results of (TD-)DFT calculations supported the structural and spectroscopic data and showed the features of electronic distribution in the frontier
