Diazonium salt formation is only possible with primary aryl and alkyl amines. The diazonium salts formation mechanism involves the addition of NO, followed by a series of acid-base reactions that turn the oxygen into water and creates a triple bond between the two nitrogens.

Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group [R−N+≡N]X− where R can be any organic group, such as an alkyl or an aryl, and X is an inorganic or organic anion, such as a halide.
One way to transform diazonium salts is by treating them with various compounds of copper. These are known as Sandmeyer reactions, after Traugott Sandmeyer who first discovered the reaction in 1884 (with copper acetylide!).
Diazonium salts are a class of organic compounds containing the diazonium functional group (-N2+X-), where X is an anion such as chloride (Cl-), tetrafluoroborate (BF4-), or sulfate (SO42-).
Diazonium salts were first obtained from aromatic amines in 1858, and their utility in the preparation of azo compounds was soon recognized by the dye industry.
Diazonium salts are a class of organic compounds characterized by the presence of the diazonium group (–N 2+) attached to an aromatic ring. Their general formula is R N 2+ X -, where R is typically an aryl group, and X - represents an anion such as Cl -, Br -, HSO 4-, or BF 4-.
Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group with the characteristic structure of R-N 2+ X - where R can be any organic residue such alkyl or aryl and X is an inorganic or organic anion such as a halogen.
The diazonium group finds application in many ways. From the dyes and pigment industry to the synthesis of various organic compounds, this combination of organic and inorganic components has been a boon for scientists.
A diazonium compound is defined as an aromatic compound that contains a diazonium group (–N₂⁺), which can be stabilized and utilized in various chemical reactions, including the preparation of diazonium salts from amines and sodium nitrite.
Diazonium salts in general are high energy materials that can decompose violently either by heating or by mechanical force (shock-sensitive), so in that sense, they may be considered self-reactive. A reaction enthalpy of -160 kJ/mol to -180 kJ/mol is associated with the diazo functional group.
