The new hybrid NHC gold(I) acetonitrile polyoxometalate complexes {[Au(IPr)(MeCN) + ][H + ] 3 [SiW 12 O 40 4− ] ( 1 ), [Au(IPr)(MeCN) + ][H + ] 2 [PMo 12 O 40 3− ] ( 2 ), [Au(IPr)(MeCN) + ][H + ] 5 [P 2 W 18 O 62 6− ] ( 3 ), [Au(IPr)(MeCN) + ][H + ] 2 [PW 12 O 40 3− ] ( 4 ), [Au(IPr)(MeCN) + ] 3 [PMo 12 O 40 3− ] ( 5 ) and [Au(I t Bu)(MeCN) + ] [H + ] 2 [PMo 12 O 40 3− ] ( 6 )} were readily synthesized in high yield and characterized by NMR and MS‐ESI spectroscopy. In a preliminary catalytic study, their activity was assessed under heterogeneous conditions for the ene‐yne rearrangement reaction and a cycloisomerization reaction. Additionally, their reactivity and recyclability were tested in the hydration of alkynes under homogeneous conditions.
