Abstract
The gold–germanium bond in the complex Ph3PAuGePh3(I) is cleaved by a variety of halides [HCl, HgCl2, CCl4, C2H4Br2, C2H4Cl2, Mel, Ph3PAuCl, and (Et3P)2PtCl2]. Oxidation by air is catalysed by peroxides. Cleavage by magnesium bromide gives the germyl Grignard reagent, Ph3GeMgBr, whilst tin(IV) chloride forms gold–tin complexes, (Ph3P)nAuSnCl3. Triethylphosphine and the chelate, Ph2PCH2CH2PPh2, displace triphenylphosphine from (I), and the former, with limited access of air, yields a triethylphosphine gold(0) complex. Carbon monoxide also gives evidence of a gold(0) complex in its reaction with (I). The trimethylgermyl complex, Ph3PAuGeMe3 is obtained in low yield by the reaction between Ph3PAuCl and (Me3Ge)2Hg.Keywords
