✦ Synopsis

The reaction behavior of a transient olefin-palladium(0) complex after the first allylation was studied. Highly efficient palladium-catalyzed cascade double alkylation of a diallylic substrate is achieved by tuning the ligands. As a result, bidentate ligands which could form cyclic catalysts with a four-methylene bridge between two phosphorus atoms were effective for high selectivity and catalytic activity.

The regioselectivity of the reaction of ethyl acetoacetate on allylic carbonate in the presence of a catalyst prepared from Pd(OAc), and P(C,H,-m-SO,Na), (or tppts) is not affected by the ratio Pd(OAc),/tppts, the nature of the nitrile, the relative amounts of water and nitrile or the temperature of
