Sodium phenoxide is an organic compound with the formula NaOC6H5. This white solid is the conjugate base of phenol. It is used as a precursor to many other organic compounds, such as aryl ethers. ==Synthesis and structure== Most commonly, solutions of sodium phenoxide are produced by treating phenol with sodium hydroxide.〔C. S. Marvel and A. L. Tanenbaum "γ-Phenoxypropyl Bromide" Org. Synth. 1929, vol. 9, pp. 72.〕 Anhydrous derivatives can be prepared from phenol and sodium: :Na + HOC6H5 → NaOC6H5 + 1/2 H2 Like other sodium alkoxides, crystalline sodium phenolate adopts a complex structures involving multiple Na-O bonds. Solvent-free material is polymeric, each Na center being bound to three oxygen ligands as well as the phenyl ring. Adducts of sodium phenoxide are molecular, such as the cubane ()4(HMPA)4.〔Michael Kunert, Eckhard Dinjus, Maria Nauck, Joachim Sieler "Structure and Reactivity of Sodium Phenoxide - Following the Course of the Kolbe-Schmitt Reaction" Chemische Berichte 1997 Volume 130, Issue 10, pages 1461–1465. 〕
