•Solvent free formation of metal nanoparticle was realized.•M@OS morphology and size distribution were controlled.•M@OS were highly active in hydroboration of alkyne.•Stereochemical outcome of the reaction was modulated by metal and onium salt change.
Metal nanocrystals have been prepared in onium salts using supercritical carbon dioxide assisted synthesis. During the process, metal salts precursors are reduced by H2 in an organic solvent free media, the onium salts allowing both the stabilization of the nanostructured material and the preparation of an air and moisture stable powder made of embedded metal nanocrystals. Those catalysts proved to be highly effective in the hydroboration of alkyne process.
