Sodium salts of sulfonated triphenylphosphine P(m-C5H4S03Na)3 or alkyltriphenyl-methyltrisulfonates function as stabilizers for hydrosols of colloidal rhodium and (C6H5)2P-p-C6H5S03Na has been used by Schmid to prepare water soluble gold clusters which are isolable and redispersible without agglomeration [202].

The majority of gold(I) carbene complexes are pure organometallic compounds and the are out of the scope of this work. Some halide or triphenylphosphine carbene complexes are known and they will be considered here. Nucleophilic addition of alcohols or amines to gold-coordinated isocyanides is one of the best-established methods to obtain gold carbene derivatives. The reaction of H[Au(CN)2] with propene oxide and estirene oxide yields (cyano)carbene complexes (380) avoiding the intermediate step.2257 A cyclic carbene compound is obtained by reaction of a dinuclear isocyanide with amine (Scheme 32).2258... 

An enantiospecific, gold-catalyzed pyrrole annelation reaction was utilized in a total synthesis of rhazinilam 95 <06JACS10352>. Specifically, treatment of allene 81 with gold triflate - triphenylphosphine led to the formation of annelated pyrrole 82, which was subsequently converted into 95. A gold-catalyzed direct coupling of pyrroles with 1,3-dicarbonyls led to the formation (3-(pyrrol-2-yl)enones <06ASC331>. 

Anionic alkoxy Fischer-type carbene complexes were shown to react with (Ph3P)AuGl to give a unique vinyl ether complex, which is bound in a quasi-771 fashion to the Cr/Mo centers. Upon treatment with triphenylphosphine, the gold-vinyl ether ligand can be liberated and isolated. This reaction thus gives access for the first time to aurated vinyl ethers (Scheme 57).38... 

Ligand-stabilized metal nanoparticles such as triphenylphosphine-stabilized gold nanoparticles were usually synthesized by reduction of the corresponding metal ions or complexes with excess diborane. Tetraalkylammonium salts of hydro-... 

The purified product can be rinsed through the frit with dichloromethane or carefully scraped off as a powder from the surface of the frit. The purity of the gold nanoparticles is confirmed by NMR spectroscopy in CDCI3. When a relaxation delay of 5 s is used, a broad resonance at 6-8 ppm with a small multiplet at 7.5 ppm (from residual (PPh3)AuCl) is observed. If the intensity of the resonance at 6 7.5 ppm due to (PPh3)AuCl is much greater than the broad resonance due to the bound triphenylphosphine ligand, then additional 1 1 pentane chloroform washes are performed until the resonance is sufficiently reduced.
