Any phenol that has substituents in a 1, 3 configuration.

Molar extinction coefficient of phenol ret at 610nM is 22 mM-1 cm-1

There is no reaction when their molar ratio is around 1...but when phenol is present in excess it gives triphenylphosphate....

phenol

There are many known syntheses of phenol. However, a few simple ones are:

1) hydrolysis of chlorobenzene:

- chlorobenzene + water --> phenol + hydrochloric acid

2) oxidation of toluene:

- toluene + oxygen --> phenol + carbon dioxide + water

3) oxidation of benzene with nitrous oxide:

- benzene + nitrous oxide --> phenol + nitrogen
