A novel visible light and heat promoted C㎡ coupling reaction of phenols and aryl halides has been described. Compared to the traditional C㎡ coupling reaction promoted by visible light, this strategy avoids use transition﹎etal, photocatalysts and ligands, and solves several problems: 1) the low...

Neither leaving groups nor catalysts are required for the electrochemical phenol–phenol cross-coupling reaction that is described by S. Waldvogel etal. in their Communication on page5210ff. The key to this sustainable synthetic method is the combination of diamond electrodes and a solvent mixture ...

I have this reaction of a diazonium salt (p-nitroaniline) was coupled with a phenol (2-napthol) to produce para red dye. Reaction:https://imgur.com/miUevH4 I am being asked to explain why coupling of p-nitrobezne diazonium chloride occurs mainly at the position that is para to the ...
The structures of reaction products between 4-amino-2,3-dimethyl-1-phenyl-3-pyrazolin-5-one and o-cresol, p-cresol, and p-ethylphenol are reported. The reaction of the former compound with phenols is used to estimate the concentration of phenol in potable water supplies. The reaction ...
