Abstract
Over the past decade, metal nanoparticles as homogeneous catalysts have attracted extensive attention for organic transformations. The metal nanoparticles as supports enhance catalyst loadings and facilitate the catalyst recovery. As active parts, metal nanoparticles stabilized by polymers and dendrimers usually witness drastically improved catalytic efficiency. Chiral molecular ligands modified metal nanoparticles endow chiral induction for asymmetric transformations. Consequently, the use of metal nanoparticles as supports or active parts provides a technically alternative approach over classical homogeneous catalysis, including hydrogenation, oxidation, carbon- carbon coupling reactions, asymmetric alkylation and asymmetric hydrosilylation etc. This brief review emphasizes on recent developments in this emerging area, covering types of stabilizers for preparing metal nanoparticles, catalytic efficiency, recyclability, enantioselectivity and catalytic mechanism.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
