The preparation, properties and X-ray structures of gold(I) trithiophosphite complexes

Synthesis and Characterization of Gold Silyl Compounds with Different Phosphine or Phosphite Groups for Reduction Reactions

“…To obtain the anticipated products, different R 3 PAuCl species are needed, whereby synthetic procedures are well known for (PhO) 3 PAuCl (2 PhO ), [17] (MeO) 3 PAuCl (2 MeO ), [18] and Et 3 PAuCl (2 Et ). With this in mind, different alterations of the compounds R 3 PAuCl and R 3 PAuSR′ [R = OPh, OMe, Et, nPr; R′ = C(SiMe 3 ) 3 , Si(SiMe 3 ) 3 ] were synthesized as described in the following, leading to a handful of yet unknown compounds that may be used as starting compounds for further reduction studies.…”

“…The obtained solids were stored in a glovebox under argon atmosphere. [18] (MeO) 3 P (0.25 g, 2 mmol) was dissolved in THF (40 mL) and (THT)AuCl (0.66 g, 2 mmol) was added. The chemical shifts are given in ppm against external standards SiMe 4 ( 1 H, 13 C, 29 Si) and 85 % phosphoric acid ( 31 P).…”

“…nPr 3 PAuCl (0.39 g, 1 mmol) was dispersed in Et 2 O (20 mL). C18 H 48 AuPSSi 4 (636.92): calcd. The cloudy white suspension stayed white and was stirred overnight.…”

Stereospecific Protodeauration/Transmetalation Generating Configurationally Stable P‐Metalated Nucleoside Derivatives

“…[32,38] Although 2 could be accessed from alkyl [39] or alkynylgold [38] precursors, we found that arylgold species were superior. [38] In terms of the bonding description for 2, the 31 P chemical shift for the {P(O)(OEt) 2 }group in 2 (δ = 111.4 ppm) [38] is shifted over 100 ppm downfield from HP(O)(OEt) 2 , and is in the range of simple phosphite gold complexes such as [{(MeO) 3 P}AuCl] [41] (δ = 121.0 ppm) and [{(PhO) 3 P}AuCl] [42] (δ = 109.7 ppm). [38] In terms of the bonding description for 2, the 31 P chemical shift for the {P(O)(OEt) 2 }group in 2 (δ = 111.4 ppm) [38] is shifted over 100 ppm downfield from HP(O)(OEt) 2 , and is in the range of simple phosphite gold complexes such as [{(MeO) 3 P}AuCl] [41] (δ = 121.0 ppm) and [{(PhO) 3 P}AuCl] [42] (δ = 109.7 ppm).…”

Synthesis of bis(trithio)phosphines by oxidative transfer of phosphorus(i)

“…In this context it is worth noting the bimetallic gold(I) complex in which the related ligand{(CH2)2S2P}SCH2CH2S{PS2(CH2)2} coordinates to two AuC6F5 groups through the two phosphine centres. 54…”
