Typical experimental procedure for preparation of nitrocompounds2: To a stirred suspension of NaH (25 mmol) in dry THF (15 mL), nitromethane (25 mmol) is added dropwise at room temperature. After stirring for 30 min, sulfone 1 4,5 (5 mmol) dissolved in dry THF (5 mL) is added and the white suspension is stirred for 1 h at room temperature. The reaction mixture is diluted with chloroform (50 mL) and washed with saturated ammonium chloride. The organic ...
