The Preparation of p-Fluorophenols from p-Aminophenols: Diazotization and Fluorodiazoniation in Pyridine-HF.

A facile preparation of p-fluorophenols is described by the diazotization of p-aminophenols and fluorodediazoniation in situ using HF in a pyridine solution (pyridine-HF) under carefully controlled conditions.

Synthesis of Polynitrodiazophenols

The formation of diazophenols by nitration of suitably substituted anilines and rearrangement of the nitroaromatic nitramines so formed is presented.The scope of the reaction is discussed, and a mechanism for the nitramine/diazophenol rearrangement is proposed which is consistent with 15N-labeling experiments.
