Abstract:

A new Mn(Ⅲ)/Mn(Ⅱ) induced reaction was developed, which involves a radical 6-endo-trig cyclization of 1-isocyano-2-[1-(trifluoromethyl)vinyl]benzene with arylboronic acid and catalyzed by manganese. Various 4-CF3-2 arylquinolines were obtained with high regioselectivity, chemical selectivity and mild condition without any external oxidants, ligands, or additives.

Key words: Mn(acac)3 induced, Isonitrile, Boronic acid, 4-CF3-quinolines
