Clusters of metals are also cores for the assembly of dendrimers which show electrochemical and biomimetic properties [63, 64], A peculiar case is represented by the stabilization of gold nanoparticles with sulfur containing dendritic ligands which provide the control of nano-architecmre dimensions for stable assemblies [65]. 

The position of copper(I) salts as quite soft Lewis acids has resulted in a significant number of publications where soft phosphorus- and sulfur-containing ligands have been used and shown to enhance the catalytic process in CuAAC reactions. A variety of phosphorus-containing ligands has been used to produce significant rate enhancements or improved efficiency in CuAAC reactions. Examples include the use of triphenylphosphine-copper(I) bromide [137] (e.g., in the synthesis of dendrimers [138]), phosphoramidites [139], and bis(triphenylphosphine)-copper(I) carboxylates [140]. In addition, triethylphosphite-copper(I) iodide complexes have been used in sugar chemistry [141].
