Abstract: The cover picture shows a two step dehydrative condensation-cyclization reaction pathway for the formation of nickel(II) complexes of porphyrinic thiazolidinones from nickel(II) 2-formyl-5,10,15,20-tetraphenylporphyrin. The first step involvesLa(OTf)3-catalyzed synthesis of 2-iminoporphyrins, whichundergo nucleophilic attack by a thiol group of mercaptoacetic acid in the second step followed by an intramolecular cyclization and a removal of H2O moleculeto afford a new series of β-substituted porphyrin-thiazolidinone hybrids. More details are discussed in the article by Bhattet al. on page200020.
