Tsuji–Trost allylations with palladium recovery by phosphines/Pd(0)-triolefinic macrocyclic catalysts

The allylation of several nitrogen and oxygen based nucleophiles with ethyl cinnamyl carbonate under mild conditions is described. The processes take place in the absence of added base and in the presence of the precatalytic system Pd(0)-triolefinic macrocycle/1,1′-bis(diphenylphosphino)ferrocene. The macrocyclic ligand plays a key role in the recovery of the metal in the form of the initial macrocyclic complex.

Allylation of nitrogen and oxygen based nucleophiles is performed with the precatalytic system Pd-1/dppf, the metal being recovered in the form of initial complex.Figure optionsDownload as PowerPoint slide
