title: Inorganic-organic heteropolyacid-gold(I) hybrids: structures and catalytic applications.
abstract: Gold(I)-polyoxometalate hybrid complexes 1-4 ([PPh3AuMeCN]xH4-x SiW12O40, x=1-4) were synthesized and characterized. The structure of the primary gold(I)-polyoxometalate 1 (x=1) was fully ascertained by XRD, FTIR, (31)P and (29)Si magic-angle spinning (MAS) NMR, mass spectroscopy, and SEM-energy dispersive X-ray spectroscopy (EDX) techniques. Moreover, this complex exhibited better catalytic activity and selectivity compared with standard, homogeneous, gold catalysts in the new rearrangement of propargylic gem-diesters.
