In the present work, a strategy for performing the hydroboration reaction of alkenes was described. The methodology employed utilizes rhodium and ruthenium nanoparticles supported on carbon nanotubes as catalysts, at a low concentration of 0.04 mol%. Additionally, the reaction was conducted under mild conditions, including room temperature and a solvent-free environment. Nine products resulting from the hydroboration reaction were synthesized, incorporating various substituents, two of which have not been previously reported. The recyclability of the catalyst was also evaluated, demonstrating its consistent efficiency over six reaction cycles. Thus, the presented methodology holds promise for the mild synthesis of boronic ester compounds, with the added advantage of catalyst reusability.
