Hydroamination of methyl methacrylate catalyzed by cationic palladium diphosphinoazine complexes

Hydroaminations of methylmethacrylate with pyrrolidine and piperidine were found to proceed without a catalyst under mild conditions. Hydroamination with morpholine catalyzed by cationic palladium diphosphinoazine complexes 1-4 was studied at temperatures 20-80 °C with catalyst loadings 0.1-1.05 mol%.
