%X In this study, we showed that the addition of randomly modified ¦Â-cyclodextrin (RAME-¦Â-CD) in aqueous medium could have a beneficial impact on the catalytic performances of phosphane-based aggregates in the Pd-catalyzed cleavage of allyl carbonates (Tsuji¨CTrost reaction). The RAME-¦Â-CD/phosphane supramolecular interactions helped explain the catalytic results. The presence of RAME-¦Â-CD in the aqueous compartment improved the phosphane-based aggregate dynamics. The exchanges between the hydrophobic substrate-containing aggregate core and the catalyst-containing aqueous phase were then greatly favored, resulting in an increase in the catalytic performances.
