Ruthenium(II)-catalyzed C-H arylation of anilides with boronic acids, borinic acids and potassium trifluoroborates
An in situ generated cationic ruthen-ium(II) catalyst allowed for robust C-H arylations of anilides with boronic acids. The optimized ruthenium catalyst was found to be both site selective and chemoselective, thereby providing the monoarylated products in
Ruthenium-catalyzed ortho-arylation of acetanilides with aromatic boronic acids: An easy route to prepare phenanthridines and carbazoles
The highly regioselective ortho-arylation of acetanilides with aromatic boronic acids in the presence of a Ru(ii) complex (3 mol%), AgSbF6 (12 mol%), Cu(OTf)2 (20 mol%) and Ag2O (1.0 eq.) is described. Later, ortho-arylated acetanilides were converted into phenanthridine and carbazole derivatives by using Ph3PO and Tf2O or palladium or Cu(OTf)2 catalysts.
