  A novel intercluster compound, [Au(PPh3)}4(μ4-O)}Au(PPh3)}3(μ3-O)}][α-PW12O40]·EtOH (1) constructed between a heptakistriphenylphosphinegold(I)}dioxonium cation and an α-Keggin polyoxometalate (POM) is synthesized and unequivocally characterized by elemental analysis, TG/DTA, FTIR, X-ray crystallography, solid-state CPMAS 31P NMR and solution (1H, 31P1H}) NMR. The heptagold(I) cluster was formed during the course of carboxylate elimination of a monomeric phosphinegold(I) carboxylate precursor, i.e., [Au((RS)-pyrrld)(PPh3)] ((RS)-Hpyrrld = (RS)-2-pyrrolidone-5-carboxylic acid), in the presence of the sodium salt of an α-Keggin POM, Na3[α-PW12O40]·9H2O. Compound 1 was formed by ionic interaction between the heptagold(I) cluster cation and the α-Keggin POM anion. The heptagold(I) cluster unit was formed by four inter-cationic aurophilic interactions between the tetragold(I) cluster unit and trigold(I) cluster unit. The tetragold(I) cluster unit and trigold(I) cluster unit contained μ4-O and μ3-O atoms, respectively.

  A DMSO-soluble intercluster compound consisting of a tetraphosphanegold(I)}oxonium cation and an a-Keggin polyoxometalate (POM) anion, [Au(PPh3)}(4) (mu(4)-O)](3)[alpha-PW12O40](2) (1), was found to be an effective precatalyst for the silver- and acid-free catalysis of diphenylacetylene hydration (0.67 mol % catalyst; conversions 36.1%, 55.2%, and 93.7% after 4, 6, and 24 h reactions, respectively). The reaction proceeded in the suspended system in 6 mL of 1,4-dioxane/water (4:1) at 80 degrees C because of the low solubility of 1. Similar POM-based phosphanegold(I) compounds [Au(PPh3)}(4) (mu(4)-O)}Au(PPh3)}(3) (mu(3)-O)}] [alpha-PWo(12)O(40)]center dot EtOH (5), which is composed of a heptakistriphenylphosphanegold(I)}dioxonium cation and an a-Keggin POM anion, and [Au(CH3CN)(PPh3)]3[alpha-PMo12O40] (6), which consists of an acid-free monomeric phosphanegold(I) acetonitrile cation and an a-Keggin molybdo-POM anion, also exhibited acid-free catalysis for the hydration of diphenylacetylene. An induction period was "observed in the catalysis by 5. On the other hand, their component species, or phosphanegold(I) species without the POM anion, such as [Au(PPh3)}(4)(mu(4)-O)](BF4)(2) (2) and [Au(PPh3)}(3)(mu(3)-O)]BF4 (3), and the monomeric phosphanegold(I) complex [Au(RS-pyrrld)(PPh3)] (4) (RS-Hpyrrld = RS-2-pyrrolidone-5-carboxylic acid), the last of which has been used as a precursor for the preparation of 1, 5, and 6, showed poor activities in this reaction (0.67 mol % catalysts; conversions 1.8%, 1.7%, and 0.5% after 24 h reactions, respectively). However, upon adding the free-acid form of Keggin POM, i.e., H-3[alpha-PW12040]-7H(2)O (H-POM: 0.67 mol %), 2-4 exhibited remarkably enhanced activities (conversion 97.6% each after 24 h reactions). In contrast, the activities were not enhanced after adding either the sodium salt of the Keggin POM, Na3[alpha-PW12O40]-8H(2)O (Na-POM; 0.67 mol %), or a Bronsted acid 10% HBF4 aqueous solution (0.67 mol %). Both HPOM and Na-POM themselves exhibited no activity. Catalysis by the phosphanegold(I) species for diphenylacetylene hydration was influenced significantly under the free-acid form or sodium salt of the Keggin POM. Acid-free catalytic hydration by 1 of other alkynes, such as phenylacetylene and 1-phenyl-1-butyne, was also examined.
