Following the procedure described for the synthesis of 3 (method A), 15.81 g (0.081 mol) of 2-bromo-1H-indene, 9.54 g (0.081 mol) of iPr2PH, 13.9 ml (10.09 g, 0.100 mol) of Et3N, and 2.95 g (2.55 mmol) of Pd(PPh3)4 in 60 ml of toluene gave 1H-Inden-2-yl(diisopropyl)phosphine. The crude product was distilled in vacuum (104–106° C./2 mm). Yield 14.8 g (80%) of colorless oil of 1H-Inden-2-yl(diisopropyl)phosphine, 4.
