実験手順

The compound bis(3-nitrophenyl)phosphinic acid (14.0 g, 45.4 mmol) from Example 1 was suspended in methanol (200 ml). Platinum (5 wt. %, on activated carbon, 1.4 g) was added. The mixture was shaken on a hydrogenation apparatus (50 psi) until no further hydrogen consumption was observed. The mixture was filtered through celite and then evaporated to dryness. The solid obtained (9.87 g, 88%) was used without purification. The structure of bis(3-aminophenyl)phosphinic acid is:
