Diazotization of amines
WebThe Balz–Schiemann reaction, which involves diazotization of the primary aromatic amines followed by fluorinative dediazoniation, could be achieved in preparative scale by carrying the reaction in PPHF, in which case the isolation of the otherwise explosive intermediary diazonium salts is not required (Figure 15).This reaction has been achieved … WebIn dieser job, we has presentation a very detailed review of of other classification of azo dyes as a function of the total of azo groups and the appropriate functional groups. Afterwards we lace going some chemical properties of these dyes such as reactivity, ...
