Versuchsvorschrift

Phenoxyacetylmethyltriphenylphosphonium chloride (10 g, 22.40 mmol) was suspended in 250 ml water with a few crystals of phenolphthalien added as an indicator. Sodium hydroxide (5%) was added dropwise until the vigorously stirred mixture turned pink. The white solid was collected, washed with water, and dried in a desicator, weight 9 g (98%); mp 127-128.5; ir (KBr, cm-1) 1595, 1580, 1540, 1480, 1435, 1400, 1225, 1105, 1045, 870; nmr (DCCl3, ppm) 7.90-6.90 (m, 21H), 4.53 (s, 2H).
