  名称：

  Phosphine-gold(I) derivatives of 1,1′-bis(alkynyl)metallocenes: Molecular structures of Fc’(CCX)2 [X = Au(PPh3), SiMe3] and Au4{(CC)2Fc’}2(PPh3)2 [Fc’ = Fe(η-C5H4-)2]

  摘要：

  Desilylation of Fc'(C = CSiMe3) 2 [1; Fc' Fe(eta-C5H4-)(2)] with LiMe or KOH/MeOH, followed by addition of AuCl(PR3), afforded Fc'{C = CAu(PR3)}(2) [R = Ph 2a, tol 2b]; the Ru analogue of 2a was also prepared. The XRD structures of 1 and 2a are reported. In the presence of CuI, a similar reaction over 2 h afforded the Au-4 cluster Au-4{(C = C)(2)Fc'}(2)(PPh3)(2) 3. The X-ray determined structure of 3 showed a planar centrosymmetric Au-4 rhomb, two opposed Au atoms being sigma-bonded to the C = C group, while the other two Au atoms are each eta(2)-bonded to the C = C group and a PPh3 ligand.
