After the oxidation, which is normally done with a peroxy acid, halogenation is done under basic conditions by use of dibromodifluoromethane for the halogen transfer step.

A common method in organic synthesis employing is the Wohl Ziegler reaction, which employs homolysis to yield a bromine radical and is a free-radical halogenation variant.

It undergoes a series of hydrogenation reactions, and it is susceptible to halogenation, Diels-Alder additions, and nitration, all with varying degrees of selectivity.

Historically the use of SOCl 2 in combination with a tertiary amine such as pyridine was called the Darzens halogenation however this name is rarely used by modern chemists.
48.
Methanol is the most important base material for industrial chemistry, where it is often used to make more complex molecules through reactions of halogenation and chemical addition reaction.
49.
Halogenation of phenols is faster in polar solvents due to the dissociation of phenol, with phenoxide ions being more susceptible to electrophilic attack as they are more electron-rich.
50.
The synthesis was completed by a halogenation-dehydrogenation sequence and subsequent bromination to yield "'18 "'and ring aromatization with elimination via a lithium complex.
