Highly selective palladium–benzothiazole carbene-catalyzed allylation of active methylene compounds under neutral conditions

Beilstein Journal of Organic Chemistry, 2015
The Pd–benzothiazol-2-ylidene complex I was found to be a chemoselective catalyst for the Tsuji–Trost allylation of active methylene compounds carried out under neutral conditions and using carbonates as allylating agents.

Impact of cyclodextrins on the behavior of amphiphilic ligands in aqueous organometallic catalysis

Beilstein Journal of Organic Chemistry, 2012
In this study, we showed that the addition of randomly modified β-cyclodextrin (RAME-β-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 ...
