ANIONIC PERFLUOROPHENYL COMPLEXES OF GOLD(I) AND GOLD(III)

The preparation of organogold(I) anions of the types [AuRX]-, [AuR2]- and [AuRR′]- (R,R′ = C6F5 or 2,4,6,-C6F3H2; X = Cl, i, SCN. CN or N3) is accomplished in which the tetrahydrothiophen group of AuR(tht) is substituted by X,R or R′. Oragnogold(III) complexes of the general formulae [Aur2X2]-, [AuRR′X2]-, [AuR3X]- and [AuR4]- (R, R′ = C6F5, 2,3,4,6-C6F4H or 2,4,6,-C6F3H2; X = Cl, Br or I) are obtained either by oxidation of the above-mentioned gold(I) complexes or by substitution reactions of AuCl3(tht). The assignment of the cis- or, respectively, trans-configuration of the [AuR2X2]- derivatives is based on their IR spectra. © 1979.
