Condition B: Under argon, to a solution of fac-Ir(d-F(p-t-Bu)ppy)3 (2 mol%), PNSF 2a or 2c (0.1 mmol, 1.0 equiv.) in dried DCM (Dichloromethane) : MA (Methyl acetate) = 1:1 (2.0 mL) was added corresponding aryl compounds 1d-1j, 1n-1p, 4aq (0.15 mmol) at room temperature. After that, the tube was exposed to a 30 W blue LEDs for 12 h until the reaction was completed as monitored by TLC analysis. The reaction mixture was evaporated in vacuo. The crude products were directly purified by flash chromatography on silica gel to give the desired products.
