Study of certain condensation products in the 2,2′-dithienyl series. III

  • A. E. Lipkin


Bis-α, β-unsaturated diketones of 2, 2′-dithienyl, which had not been previously described in the literature, were synthesized by means of a crotonic condensation of 5, 5′-diacetyl-2, 2′-dithienyl with certain aromatic and heterocyclic aldehydes. These compounds form halochromic solutions in sulfuric acid. The IR and UV spectra were determined.
