Synthesis of diazonaphthoquinones from naphthols by diazo-transfer reaction with 2-azido-1,3-dimethylimidazolinium chloride
An efficient synthetic method for the synthesis of diazonaphthoquinones from naphthols is described. A variety of diazonaphthoquinones were synthesized from the corresponding naphthols by the diazo transfer with 2-azido-1,3- dimethylimidazolinium chloride prepared by the reaction of 2-chloro-1,3- dimethylimidazorinium chloride and sodium azide.
