Regioselective Monobromination of Free and Protected Phenols

European Journal of Organic Chemistry, 2007
AbstractA comparative study of the advantages of using THF compared with DMF in regioselective monobromination reactions of highly activated polyphenols, their ethers, and their tert‐butyl carbonate derivatives under mild conditions is described. Bromination with the common reagent N‐bromosuccinimide in polar solvents provided an easy and fast approach

On the determination of free phenol in phenol‐formaldehyde resins

Recueil des Travaux Chimiques des Pays-Bas, 1958
AbstractThe time necessary for the determination of free phenol in phenol‐formaldehyde resins and moulding powders can be appreciably reduced by the addition of glycol to the resin during the steam distillation.

Cation–anion CH⋯O− interactions in the metal-free phenolate, tetra-n-butylammonium phenol-phenolate

Tetrahedron, 2002
Abstract Deprotonation of phenol by tetra-n-butylammonium hydroxide and subsequent removal of water by P2O5 results in quantitative formation of tetra-n-butylammonium phenol-phenolate. The compound crystallizes as an ion pair, with the solute phenol molecule intimately attached to the phenolate anion by an O–H⋯O− hydrogen bond (O⋯O 2.471(5) A).
