Hydroamination of Aromatic Alkynes to Imines Catalyzed by Pd(II)–Anthraphos Complexes
2020
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.
