Title: Direct hydroxylation of arenes
Post by: mir on February 06, 2006, 04:59:36 AM

Is there any procedures for this hydroksylation:

Ar-H + R-OH --> Ar-OH + R-H

The reaction have to go in one step. Good or bad yield, does not matter as long as the reaction work in reasonable environment, like approximatly STP.
I checked up my organic chem book (Author: Ege) with no results. One possibility in another book used high pressures. This is not an option.

Thank you for all your answers.
