The First Acetimine Gold(I) and Gold(III) Complexes and the First Acetonine Complexes

“…We have previously reported [38,39] (5) which accounts for both the low yield of pure 4 and the growth of single crystals of 5 (see Figure 1) from solutions of 4.…”

“…Synthesis of imino complexes of gold(i) and (iii): Ketimino-(phosphino)gold(i) complexes of the type [Au{N(R) C(Me)R'}L]X (1 ± 3'; Scheme 2, method A) were synthesized by reacting equimolar amounts of [Au(acac)L] (acac acetyl acetonate) [37] and ammonium salts, [RNH 3 ]X, dissolved in the appropriate ketone MeC(O)R'. We have previously reported [38,39] (5) which accounts for both the low yield of pure 4 and the growth of single crystals of 5 (see Figure 1) from solutions of 4.…”

“…In several reactions meant to establish the generality of this method for the synthesis of imino(phosphino)gold(i) complexes we have found that 1) complexes [Au(n-NH 2 C 6 H 4 NO 2 )-(PPh 3 [39] Complexes [Au(NHCMe 2 ) 2 ]X (X ClO 4 (6), OTf (6')) were obtained in good yields by stirring [Au(NH 3 ) 2 ]X (X ClO 4 or OTf) [39] in acetone for five days (Scheme 3). The Scheme 3.…”

Heteropolynuclear Phosphide Complexes: Phosphorus as Unique Atom Bridging Coinage Metal Centres

“…After stirring for 1 h, the solvent was partially evaporated and hexane was added to afford 9 as a white solid (0.16 g). Yield: 54 %; 31 Synthesis of PPN[Au(C 6 F 5 ) 3 (acac)] (12): Tl(acac) [33] (0.030 g, 0.1 mmol) was added to a solution of PPN[Au(C 6 F 5 ) 3 Cl] [34] (0.127 g, 0.1 mmol) in toluene (20 mL). The mixture was stirred for 8 h at 120 8C, and the TlCl formed was filtered off.…”

“…Yield: 58 %.Method B: Compound 2 (0.1 g, 0.1 mmol) was added to a solution of [Au(acac)(PPh 3 )][33] (0.112 g, 0.2 mmol) in dichloromethane (20 mL). The resulting solution was stirred at room temperature for 1 h and then concentrated in vacuo to % 5 mL.…”
