General description

4,5-Dibromo-2,7-di-tert-butyl-9,9-dimethylxanthene is a heterocyclic building block.

Application

4,5-Dibromo-2,7-di-tert-butyl-9,9-dimethylxanthene may be used as starting reagent for the synthesis of 4,5-(N,N′-bis-cyclohexylamino)-2,7-di-tert-butyl-9,9-dimethyl-xanthene and oligothiophene tweezer molecule bearing two quaterthiophene moieties.
4,5-Dibromo-2,7-di-tert-butyl-9,9-dimethylxanthene may be used in the synthesis of:
  • 2,7-di-tert-butyl-4,5-diiodo-9,9-dimethylxanthene
  • new NON-donor ligand, 4,5-bis(2,6-diisopropylanilino)-2,7-di-tert-butyl-9,9-dimethylxanthene
  • bis(diethylamino)xantphos, via one-pot metalation reaction and and quenching with bis(diethylamino)chlorophosphine
