Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Gold(I)‐polyoxometalate hybrid complexes <bold>1</bold>–<bold>4</bold> ([PPh₃AuMeCN]_{<italic>x</italic>}H_{4−<italic>x</italic>}SiW₁₂O₄₀, <italic>x</italic>=1–4) were synthesized and characterized. The structure of the primary gold(I)–polyoxometalate <bold>1</bold> (<italic>x</italic>=1) was fully ascertained by XRD, FTIR, ³¹P and ²⁹Si 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 <italic>gem</italic>‐diesters.</p> </abstract>
