N2 - The ion pair formed from rhodium trichloride and methyltrioctyl-ammonium chloride (Aliquat®-336) was shown to catalyze, under mild conditions, hydrogen transfer from polymethylhydrosiloxane (PMHS) to substituted acetylenes, olefins, aroyl chlorides, α,β-unsaturated aldehydes ketones and esters and saturated carboxyl compounds, respectively. Addition of aqueous sodium perchlorate to the reaction mixtures at low to medium conversions allowed facile recovery of the catalyst as aqueous NaRhCl4 which, with fresh Aliquat-336, could be re-extracted into a new reagent-containing organic solution.
