The inter-triangular diphosphine bridge in [AuMn2(CO)8(μ-PPh2)]2(μ-P−P) turns into an intra-triangular one as it undergoes amine-oxide-promoted decarbonylation to give (P−P)AuMn2(CO)7(μ-PPh2) (P−P ...

General synthesis of ferrocenylphosphine-bridged digold carboxylato complexes crystal and molecular structure of Au2(η1-CF3CO2)2(η-dppf) · C6H14 (dppf = Fe(C5H4PPh2)2)

Metathesis of Au 2 Cl 2 ( μ -dppf) with Ag(RCO 2 ) (R = CH 3 , CF 3 , C 2 H 5 and C 6 H 5 ) gives Au 2 ( η 1 -RCO 2 ) 2 ( μ -dppf) in 75–97% yields. Spectroscopic data are consistent with a common structure containing a ferrocenyl diphosphine br

Redox condensation of PPN[Mn2(CO)8(μ-PPh2)] (1; (PPN = N(PPh3)2) with Au2Cl2(μ-P−P) (P−P = (C5H4PPh2)2Fe (dppf), Ph2PC2H4PPh2 (dppe)) gives two hexanuclear Au−Mn clusters [AuMn2(CO)8(μ-PPh2)]2(μ-P−P) (P−P = dppf, (2), dppe (4)), both of

Reduction of MCl2(η2-dppf) with NaBH4 gives M(η2-dppf)2 (M  Pt, 1, Pd, 2). Oxidation of 1 or 2 with S8 gives the tetrasulfido complex M(η2-S4)(η2-dppf). Addition of 1 or 2 to Fe3 (μ3-S)2(CO)9 results in the heterometallic complex (CO)6Fe2(μ3
