 The nitrate complex Ph3PAuONO2 and the oxonium species [(Ph3PAu)3O]+[BF4]– are also prepared from the chloride.As shown in the scheme below, the methyl complex Ph3PAuMe is prepared from triphenylphosphinegold(I) chloride by transmetalation with a Grignard reagent.Further treatment of Ph3PAuMe with methyllithium displaces the phosphine ligand and generates lithium dimethylaurate, Li+[AuMe2]–.
