ChEBI: Phenoxyacetic acid(122-59-8) is a monocarboxylic acid that is the O-phenyl derivative of glycolic acid. A metabolite of 2-phenoxyethanol, it is used in the manufacture of pharmaceuticals, pesticides, fungicides and dyes. It has a role as a human xenobiotic metabolite, an Aspergillus metabolite, a plant growth retardant and an allergen. It is a monocarboxylic acid and an aromatic ether. It is functionally related to a glycolic acid. It is a conjugate acid of a phenoxyacetate.
| [Preparation]
By reacting phenol and monochloroacetic acid. | [Synthesis Reference(s)]

A Schlenk tube was charged with aryl iodides (1) (1.0 mmol), glycolic acid (228 mg, 3.0 mmol), CuI (19.0 mg, 0.1 mmol), Cs2CO3 (1.95 g, 6.0 mmol), and DMSO/H2O (2 mL/1 mL). The mixture was stirred for 24 h at 120 ℃ under Ar. The reaction mixture was allowed to cool to room temperature, poured into 5 mL of water, and then acidified to pH = 1 with 2 N HCl solution. The aqueous phase was extracted twice with EtOAc, and the combined organic layer was washed with H2O and brine, dried over anhydrous MgSO4, and concentrated under vacuum. Purification of the crude product by column chromatography (dichloromethane/methanol) afforded the desired product Phenoxyacetic acid, white solid, yield 133 mg, 88%.
