Copper-Catalyzed Radical Cyclization of Aryl Amines


Typical Procedure (X = Cl, Y = O, n = 1, R1, R2 and R3 = H):
To a dried Schlenk-tube containing 2-(allyloxy)aniline (0.5 mmol, 74.6 mg, 1 eq.), tert-butyl nitrite (0.55 mmol, 56.7 mg, 1.1 eq.) in acetone (5.0 mL) at 0 °C, Cu(CH3CN)4BF4 (0.05 mmol, 15.7 mg) and conc. HCl aq (2.5 eq.) are added. The reaction mixture is warmed to room temperature and stirred for 3 h. After completion, most of the solvent is removed in vacuo and the residue is purified by flash chromatography on silica gel (eluent: pentane) to afford 3-(chloromethyl)-2,3-dihydrobenzofuran as a colorless oil (0.46 mmol, 77.6 mg, 92% yield).
