Platinum-Catalyzed Intermolecular Hydroamination of Vinyl Arenes with Carboxamides
摘要:
Reaction of benzamide with 4-methylstyrene catalyzed by a 1:2 mixture Of [PtCl2(H2C = CH2)](2) and P(4-C6H4CF3)(3) (5 mol %) in mesitylene at 140 degrees C for 24 h led to the isolation of M(1-p-tolylethyl)benzamide in 85% yield. Electron-rich, electron-poor, and hindered vinyl arenes underwent Markovnikov hydroamination with a range of carboxamides and amide derivatives in moderate to good yield with excellent regioselectivity.
