Some difficulty arose in the presentation o’wing to. The hydroxyl group is a strong activating substituent and would direct aromatic ring chlorination to locations ortho & para to itself, leading to the wrong product.

As an alternative, the nitro group is not only meta-directing, it can be converted to a hydroxyl group by way of a diazonium intermediate. The resulting strategy is self evident. The Chemistry of Diazonium and Diazo Groups, Part 2.

The "azo" bit of the name refers to nitrogen. The ionic equation for the reaction is: Notice that the chloride ions from the acid aren't involved in this in any way.

This book is a critical, well referenced and eminently readable introduction to the chemistry of aromatic and heteroaromatic diazo compounds.

It provides well researched information that could otherwise be obtained only by costly and time-consuming searches of multi-volume treatises and the original literature. What are Diazonium Salts.

The diazonium salts (di refers to ‘two’, azo is indicative of ‘nitrogen’ and ium implies that it is cationic in nature), or diazonium compounds, arethe class of organic compounds with general formula R−N 2 + X − where X is an organic or inorganic anion (for example, Cl –, Br –, BF 4 –, etc.) and R is an alkyl or aryl group.

Diazo coupling reactions. The most widely practiced reaction of diazonium salts is azo coupling. In this process, the diazonium compound is attacked by, i.e., coupled to, electron-rich substrates.

When the coupling partners are arenes such as anilines and phenols, the process is an example of electrophilic aromatic substitution. The most important application of diazo coupling reactions is electrophilic aromatic substitution of activated benzene derivatives by diazonium electrophiles.

The products of such reactions are highly colored aromatic azo compounds that find use as synthetic dyestuffs, commonly referred to as azo dyes. (source: Nielsen Book Data) Summary This text provides a homogenous presentation of aspects of diazo chemistry.

It is practice-oriented due to a strong emphasis on applications and includes many tables, schemes and literature citations.

It should be a useful reference work for synthetic organic chemists. (source: Nielsen Book Data). The most useful substrates for diazo group transfer are those possessing active methylene groups.

For example, diazo transfer to β-dicarbonyl compounds from sulfonyl azides is performed in the presence of tertiary amine bases (Scheme 56).Because of the mildness, simplicity and reliability of this reaction, it has replaced amine diazotization as the method of choice for the preparation of α.

The nitrogen (N 2) is a very good leaving group because it is a gas and once when it formed it leaves the reaction mixture. This makes the reaction irreversible. Synthesis of phenol – When an aryl diazonium salt is heated in the presence of water, the diazo group is replaced with a hydroxyl group.

Arene diazonium salts are highly reactive compounds due to the excellent leaving ability of the diazo group as Nitrogen gas (N2). Diazonium salts undergo coupling reactions with phenol (in pH 9 – 10) and amines (in pH 4- 5). The reaction is an example of an electrophilic substitution reaction in which diazonium cation with a positive.

By the author of Color Chemistry. Diazo compounds play an important role as reaction intermediates and reagents in organic synthesis. This book is a critical, well referenced and eminently readable introduction to the chemistry of aromatic and heteroaromatic diazo compounds.

It provides well researched information that could otherwise be obtained only by costly and time-consuming searches. The diazo group is an organic moiety consisting of two linked nitrogen atoms at the terminal l charge neutral organic compounds containing the diazo group bound to a carbon atom are called diazo compounds or diazoalkanes and are described by the general structural formula R 2 C=N + =N –.The simplest example of a diazo compound is diazomethane, CH 2 N 2.

Diazonium salts are a group of organic compounds which share a common functional group R – N 2 + X – where R denotes some organic residue (such as an alkyl or aryl group) and X is an organic or inorganic anion (a halogen, for example).

Diazonium salts in which R is an aryl group are significant intermediates in the organic synthesis of azo. This book is a critical, well- referenced and eminently readable introduction to the chemistry of aliphatic, inorganic and organometallic diazo compounds.

It provides well-researched information that could otherwise be obtained only by costly and time-consuming searches of multi-volume treatises and the original literature. Excerpt from The Chemistry of the Diazo-Compounds The diam-compounds were discovered in by Johann Peter Griess,* who Obtained them by treating aromatic amino compounds with nitrous acid.
