Chemical process for preparing di-ortho benzyl phenols
TL;DR: Phenols having an unsubstituted ortho-position are benzylated by reaction with a benzyl alcohol in contact with an activated alumina catalyst especially gamma alumina at a temperature sufficient to maintain the reactants in the vapor phase as mentioned in this paper.

Process for the monobenzylation of p-substituted phenols
TL;DR: In this article, a process for the preparation of p-substituted o-benzylphenols by reaction of psubstitized phenols with optionally substituted benzyl halides, benzyl esters or benzyl ethers in the presence of an acid catalyst at elevated temperature in a distillation column is described.
Patent
Production of o-benzylphenol
TL;DR: In this article, a method to produce a titled compound useful as a synthetic intermediate of organic compounds, especially pharmaceuticals, suppressing the production of by-products, by adding benzyl alcohol to phenol containing a catalyst, and reacting the components.
Patent
Aromatic coupling process
TL;DR: In this article, 4-(2-Cyano-4-nitrophenyl)phenols are prepared by reacting a 3-cyano-1-nitrobenzene having a replaceable hydrogen in the 4-position with a phenol having a replacement in the position in an inert solvent and in the presence of a strong base.
