(Chemical Equation Presented) Palladium(0) nanoparticle has been used as an efficient catalyst for the allylation of active methylene compounds. Very efficient bisallylation is achieved for a variety of active methylene compounds by allyl acetate and its derivatives in one stroke in THF solvent. The reaction in water provides monoallylated product selectively by allyl acetate only. The recovered Pd(0) nanoparticle is recycled. A probable mechanism is suggested.

The oxidative coupling of β-carbonyl imines and allyltrimethylsilane with CTAN were investigated in CH3CN and CH2Cl 2. In CH3CN allylation products were obtained predominantly, while in CH2Cl2, dihydropyrrole products were obtained exclusively. Solvent-assisted nucleophilic cleavage of the intermediate β-silyl cation is proposed to play a role in the solvent-dependent chemoselectivity.

A method is proposed for the C-alkylation of cyclic β-diketones by allyl acetate in a weakly acidic medium with Pd(PPh3)4 as catalyst.The method makes it possible to obtain high yields of the corresponding mono- and diallylated products.
