Chemistry Organic Building Blocks Diazoes
The diazo group, which is present in organic chemistry, is composed of two nitrogen atoms linked together (azo, −N=N−) and situated at the end position.
Overall 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 R2C=N+=N-.
Diazomethane, CH2N2, is the most basic illustration of a diazo compound (R2C=N2), which should not be mistaken for azo compounds (R−N=N−R) or diazonium compounds (R−N2+).
Diazo compounds are compounds in which the electronic structure is marked by π electron density that is distributed over the α-carbon and two nitrogen atoms, and they also possessan orthogonal π system that has electron density delocalized over only the terminal nitrogen atoms.
Diazo compounds belong to a class of compounds known as 1,3-dipoles due to the presence of formal charges in all of their octet rule-satisfying resonance forms.
