Phase-transfer Tsuji-Trost allylation of CH-acids with the assistance of palladium complexes with bidentate PIII-N-PIII ligands

The Tsuji-Trost allylation of CH acids, in particular, those of the YCH2CO2Et type (Y = CO2Et, C(O)Me, CN), with allylic acetates in the K2CO3-DMF system in the presence of palladium catalysts with ligands RN(PPh2)(2) (R = Ph, Pr-i, c-C6H11) is accomplished.
