Mild Ullmann-type biaryl ether formation reaction by combination of ortho-substituent and ligand effects

(Chemical Equation Presented) An important position: A strong orthosubstituent effect caused by NHCOR groups in 2-haloacetanilides in combination with the ligand effect greatly promotes an Ullmann-type biaryl formation reaction that takes place at room te
