Solvent-free Microwave-Assisted Ortho-Alkylation of Aromatic Ketimine with Acrylic Acid Derivatives by Rh(I) Catalyst

[摘要] Microwave(MW)-assisted ortho-alkylation of aromatic imine with acrylic acid derivatives was performed in the presence of a (PPh3)3RhCl catalyst, and corresponding ortho-alkylated ketones were obtained after hydrolysis of the resulting ketimines. This solventless MW-assisted ortho-alkylation was highly efficient compared with conventional heating, probably due to the specific MW effect.
