Catalytic Reduction of ortho- and para-Azidonitrobenzenes via tert-Butoxide Ion Mediated Electron Transfer
摘要:
The reduction of a range of substituted azidonitrobenzene derivatives to the corresponding aniline is described. The chemoselective reaction proceeds cleanly and in good yield, generating minimal waste products. The process involves a thiazolium salt derived species which is proposed as a radical anion relay, with tert-butoxide as the stoichiometric reductant.

controlled by custom software created in-house was used to collect the aryl azide stream and restore it to a continuous column of the reagent. When combined with a variety of dipolarophiles, 1-aryl-[1,2,3]-triazoles were thus assembled by either copper catalyzed alkyne–azide cycloaddition (CuAAC) or Huisgen cycloaddition reactions. ̀

compounds 10a‐n were evaluated for their cytotoxic activity against the MCF‐7 cell line (Human breast cancer cell line) at different concentrations of 0.625, 1.25, 2.5, 5, and 10 μM, respectively. The cytotoxic evaluation assay is presented in terms of IC50 values and percentage cell viability reduction compared against standard drug cisplatin. Among all novel synthesized compounds 10a‐n, some of the
