Treatment of with (x=o, m, or p) gives anionic gold(I) complexes of the type (R=o-, m- or p-C6H4NO2, Bz=C6H5CH2).The chloro ligand in ^- can be replaced by bromo or iodo ligands by use of NaBr or NaI.The anions ^- react with neutral monodentate ligands, L, to give neutral mononuclear complexes (R=o-C6H4NO2, L=PPh3, AsPh3; R=m-C6H4NO2, L=PPh3) and with 1,2-bis(diphenylphosphino)ethane (dpe) to give (R=o-C6H4NO2).The corresponding ^- reacts with PPh3 or AsPh3 to give mixtures containing .The anionic ortho-nitrophenylgold(I) complex is much more stable than its meta- or para-nitrophenyl isomers.These are thought to be the first reports of nitrophenylgold(I) complexes.
