The new hybrid NHC gold(I) acetonitrile polyoxometalate complexes {[Au(IPr)(MeCN) ][H ] [SiW O ] (1), [Au(IPr)(MeCN) ][H ] [PMo O ] (2), [Au(IPr)(MeCN) ][H ] [P W O ] (3), [Au(IPr)(MeCN) ][H ] [PW O ] (4), [Au(IPr)(MeCN) ] [PMo O ] (5) and [Au(ItBu)(MeCN) ] [H ] [PMo O ] (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.
新型杂化 NHC 金（I）乙腈多金属氧酸盐配合物{[Au(IPr)(MeCN)][H][SiW12O40]（1），[Au(IPr)(MeCN)][H][PMo12O40]（2），[Au(IPr)(MeCN)][H][PW12O40]（3），[Au(IPr)(MeCN)][H][PW12O40]（4），[Au(IPr)(MeCN)][PMo12O40]（5）和[Au(ItBu)(MeCN)][H][PMo12O40]（6）}可高产率地合成，并通过 NMR 和 MS-ESI 光谱进行了表征。在初步的催化研究中，在非均相条件下评估了它们对烯炔重排反应和环异构化反应的活性。此外，还在均相条件下对炔烃的水合反应测试了它们的反应性和可回收性。
