NEW ORGANOGOLD COMPLEXES: TETRAPHENYLCYCLOPENTADIENE DERIVATIVES

Mono- and diaurated derivatives of tetraphenylcyclopentadiene, Ph4C5HAuPPh3 and Ph4C5(AuPPh3)2, have been obtained by auration of tetraphenylcyclopentadiene with tris(triphenylphophinegold)oxonium tetrafluoroborate.Under the action of +BF4- both mono- and diaurated derivatives form the trinuclear cationic complex +BF4-, which is converted into Ph4C5(AuPPh3)2 when treated with nucleophiles.The structure of Ph4C5HAuPPh3 and +BF4- was established by IR, UV, PMR spectral and X-ray structural studies.Ph4C5HAuPPh3 has a C-Au bond and additional coordination of Au with two neighboring carbon atoms of the five-membered ring; the structure is non-fluxional.The complex +BF4- includes rather rare structural moieties: a three-membered carbometal cycle , three gold atoms linked to each other, Au-Au-Au, and univalent gold coordinated with three carbon atoms of the Ph4C5 ring.
