Synthesis of new 4,4?-bis(arylethynyl)benzophenones and 4,4?-bis(arylglyoxalyl)benzophenones based on chloral
摘要:
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 catalyst; further oxidation of rile products obtained in an iodine/DMSO medium afforded new bis(arylglyoxalyl)benzophenones.
