A novel and simple procedure for the construction of fully substituted thiophene-2,4-diamines using tertiary thioamides was developed. Thus, thioacetomorpholides undergo self-condensation to the corresponding 3,5-diarylthiophene-2,4-diamine derivatives in the presence of iodine and potassium carbonate in a suitable solvent and under mild conditions.

Starting from N,N,C-triarylacetamides and 1-aryl-2-bromoethanones a series of new 3,4-diaryl-substituted 2-diarylaminothiophenes have been prepared and characterized spectroscopically.
By using the well-known Hantzsch method and starting from some mono- and bifunctional aryl-substituted thioureas, thioacetamides, and bromoketones several new aryl-substituted 2-aminothiazoles and 2-aminothiophenes have been prepared and tested as hole transport materials for OLEDs.

The oxidative coupling of N,N-disubstituted 2-aminothiophenes performed by several heavy-metal free oxidizing agents gives rise to the formation of N,N′-persubstituted 5,5′-diamino-2,2′-bithiophenes which are of interest as hole-transport materials for optoelectronic applications.

A new one‐step synthesis of highly substituted thiophen‐2(3H)‐one derivatives was developed. 2‐Aryl‐1‐(morpholin‐4‐yl)ethanethiones were reacted with 2‐chloro‐2‐phenylacetyl chloride in DMF in the presence of a base to give the title compounds in moderate‐to‐good yields.
