Diazo reaction mechanism
WebAnswer: Diazo Compounds are Compounds containing -N=N- group which are known as diazo compounds. Their general structure is R-N=N-R’ Here R and R’ are preferably arene groups and the azo group is thus stabilised by becoming part of extended delocalised system. They are prepared by coupling reacti...

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 ... WebThe 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. 1. Synthesis of phenol – When an aryl diazonium salt is heated in the presence of water, the diazo group is replaced with a hydroxyl group and phenol is formed.
