N-heterocyclic carbenecopper(I) complex functionalized conjugated microporous polymer (CMP-NHC-CuCl) was synthesized by palladium-catalyzed Sonogashira cross-coupling chemistry. The resulting CMP-NHC-CuCl proved to be a good heterogeneous catalyst in the hydrosilylation of functionalized terminal alkynes with boryldisiloxane to afford (β,β)-(E)-vinyldisiloxane with high stereoselectivity, and the catalyst could

Tubular microporous organic networks bearing imidazolium salts (T-IM) were prepared by Sonogashira coupling of tetrakis(4-ethynylphenyl)methane and diiodoimidazolium salts, which showed promising catalytic activities in heterogeneous conversion of CO2 into cyclic carbonates.
Macrocyclic dinuclear complexes have been gaining popularity in the design of homogeneous catalysts. Herein, we report the design of such a complex featuring catalytically active sites fixed inside the ring and its synthesis using a cross-coupling reaction.

By combining a Pd-catalyzed Migita cross coupling and mechanosynthesis, a series of azoliums and Ag(I)-N-heterocyclic carbenethioglycoside complexes were synthesized. This new family of carbohydrate derived NHCs displays promising potential as catalysts as well as bioactive compounds.
A Au(I)–N-heterocyclic-carbene (NHC)-edged Pd6L12 molecular metal–organic cage is assembled from a Au(I)–NHC-based bipyridyl bent ligand and Pd2+. The octahedral cage structure is unambiguously established by NMR, electrospray ionization-mass spectrometry and single crystal X-ray crystallography. The electrochemical behaviour was analyzed by cyclic voltammetry. The octahedral cage has a central cavity
