Synthesis of new 4,4′-bis(arylethynyl)benzophenones and 4,4′-bis(arylglyoxalyl)benzophenones based on chloral

Article abstract of DOI:10.1007/BF01435794

4,4′-Diiodobenzophenone was obtained by a three-stage synthesis from chloral and iodobenzene. 4,4′-Bis(arylethynyl)benzophenones were synthesized by cross-coupling of 4,4′-diiodobenzophenone with terminal arylethynes in the presence of a complex Pd cataly
