Abstract
The reaction of allylic carbonates with various acyclic and cyclic carbonucleophiles is catalyzed by the system Pd(OAc) 2 and P(C 6H 4- m-SO 3Na) 3 (or tppts) in a two-phase liquid medium H 2O-nitrile, the activity of the catalyst depending mainly on the nature of the nitrile, the temperature of the reaction and the ratio palladium/tppts. The same system Pd(OAc) 2 and P(C 6H 4- m-SO 3Na) 3 supported on silica catalyzes also this reaction. The formation of the active palladium species in the two cases is followed by 31 P NMR spectroscopy and discussed.
