Gold species, dinuclear

A related dinuclear species 77, recently described, constitutes the first dinuclear gold(I) complex with heterobridged phosphor-1,1 -dithiolato moieties and bis(ylide) bridging ligands [ 102]. It is obtained by reaction between [ AuS2PPh2] and the diylide gold complex 74 (R=Me). No intermolecular Au-Au interaction is observed in 77 but the oxidative addition of chlorine to the product leads to a new complex 78 in which a single bond is formed between the two Au(II) centers (Scheme 26). [Pg.61]

The differences observed in the chemistry of these dinuclear gold(I) amidinate complexes compared with dinuclear gold(I) complexes with sulfur and carbon ligands may be understood by examining their respective highest occupied molecular orbital (HOMO)s and lowest unoccupied molecular orbital (LUMO)s of the species. [Pg.15]

The reaction of the dinuclear gold(I) complex [Au2 //-2,6-(NMe2CH2)C6H3 2] with an excess of CH2I2 affords the gold(III) ammonium species (Equation (19)).19... [Pg.1012]

As earlier mentioned, one of the reasons of the poor stability of gold(II) complexes is the unfavorable energy of the odd electron. The formation of a metal—metal bond in dinuclear gold(II) complexes giving diamagnetic species provides an extra stability. Thus, the number of... [Pg.1018]
