実験手順
3.6 g (10.83 mmol) 4,4′-Dinitro-1,1′-biphenyl-2,2′-dicarboxylic acid are dissolved in 25 ml tetrahydrofuran and added dropwise in a the course of 1 hours to 65 ml (65.02 mmol) of a borane-tetrahydrofuran complex 1.0 M solution in tetrahydrofuran. After 19 hours at 25° C., 50 ml water are carefully added. After 1 h the solution is acidified to pH=1-2 with 10 ml 1N HCl solution and allowed to stirred for 30 min. The reaction mixture is then partitioned between ethyl acetate and water; the organic phase is washed repeatedly with water, dried over sodium sulfate, filtered and concentrated by rotary evaporation. The residue, 4.2 g of 2,2′-bis(hydroxymethyl-4,4′-Dinitro 1,1′-biphenyl as white powder is used without further purification.
