摘要

Aryl hydrazines are highly valuable intermediates in the synthesis of a number of important nitrogen-containing heterocyclic frameworks such as indoles (through the Fischer indole synthesis),[1] indazoles, aryl pyrazoles, and aryl triazoles.[2] In some cases, hydrazine reacts with haloarenes directly in nucleophilic aromatic substitution reactions; however, such reactions typically occur at high temperatures, and/or only with highly electron-deficient ...
