Abstract

Herein, we report the synthesis, characterization, and catalytic performance of cationic Pd(II)-Anthraphos complexes in the intermolecular hydroamination of aromatic alkynes with aromatic amines. The reaction proceeds with 0.18 mol % of catalyst loading, at 90 °C for 4 h under neat conditions. Good to excellent yields could be obtained for a broad range of amines and alkynes.
