Gold(I)‐polyoxometalate hybrid complexes 1 – 4 ([PPh 3 AuMeCN] x H 4− x SiW 12 O 40 , 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.
