9-Methyl-9,10-dihydro-9-phosphaphenanthrene-9-oxide (3).1 The phosphonium salt 2 (R = Me, 0.7 g, 1.5 mmol) in aq acetone containing KOH solution was heated to reflux for 2 h. Extraction of the cold mixture with CHCl3, evaporation of the solvent and silica gel chromatography via elution with EA:EtOH (7:3) afforded 0.24 g, 71% of 3.

Hydroxyphosphine oxide (8).6 Benzoyl chloride (10 g, 71.1 mmol) was added to 4 (7.53 g, 40 mmol) and Et3N (20 mL) in Et2O (300 mL). After 3 h stirring under reflux 5 was hydrolyzed with water (150 mL) for 2 h. The precipitates thus formed were removed by filtration and the resulting filtrate dried over MgSO4. Evaporation of the solvent and recrystallization from PhCH3 afforded 10.8 g of 8 (87%).
