چکیده
Both monoand bisylide zwitterionic complexes of gold(I), [(C6F5){PhCH(PPh3)}Au] (4), [(C6F5)2(C6H4-p){CH(PPh3)}2Au2] (5) and [(C6F5)2(C6H4-m){CH(PPh3)}2Au2] (6) were prepared by THT substitution in [C6F5(THT)Au] (THT = tetrahydrothiophene) using deprotonated monoand bis-phosphonium salts. Lithiation of 4,4′-dibromo-2,3,5,6,2′ ,3′,5′,6′-octafluoro-1,1′biphenyl and transmetallation with [Cl(Ph3P)Au] produced a dinuclear gold complex of octafluorosubstituted biphenyl [[(PPh3)2(C6F4-C6F4)2Au2]] (8).
