Tris(triphenylphosphinegold)oxonium salts

A porphyrin complex of Gold(I): (Phosphine)gold(I) azides as cation precursors

“…Finally, we note that the gold(I) oxonium complexes of Nesmeyanov and coworkers (61)(62)(63)(64)(65) are convenient sources of R 3 PAu ϩ equivalents. To our knowledge, no (N-heterocyclic carbene)gold(I) analogues have been reported; neither have oxonium cations bearing encumbrancing dialkylbiaryl phosphine ligands emerged.…”

The Role of Secondary Interactions in Group 11 Metal Complexes Containing the Ferrocene Ligand FcCH2NHpyMe in Supramolecular Structures

“…C, H, N and S analyses were carried out with a PerkinϪElmer 2400 microanalyser. Mass spectra were recorded [14] [O(AuPPh 3 ) 3 ]ClO 4 , [15] [Au(C 6 F 5 )(tht)], [16] [Au(C 6 F 5 ) 3 (OEt 2 )], [17] [Au(C 6 F 5 ) 2 Cl] 2 [18] and [Ag(OTf)(PPh 3 )] [19] were prepared according to published procedures. All other reagents were commercially available.…”

“…The AuϪN distances are 2.091(5) Å to the pyridine nitrogen atom and 2.052(5) Å to the amine nitrogen atom which are among the longest found in Figure 1.

Synthesis of a Tri(gold)boride Complex (Cy3P)B[AuP(o-Tol)3]3

“…Cy 3 BH 2 SiMe 3 was prepared following a procedure published previously [19]. Tri(gold)oxonium salts were also obtained according to syntheses described in the literature: R 3 P = Ph 3 P [22], Cy 3 P [23], (o-Tol) 3 …”
