Morphology and size controllable rhodium nanoparticles stabilized by a nitrogen‐rich polyoxyethylenated derivative have been prepared by reduction of RhCl 3 with NaBH 4 in water at room temperature and fully characterized. The flower‐like Rh NPs are effective and recyclable catalysts for the stereoselective hydrosilylation of challenging internal alkynes and diynes, affording the ( E )‐vinylsilanes in quantitative yields for a wide range of substrates. The insolubility of the nanocatalyst in diethyl ether allows its easy separation and recycling.
