Yield: 81%
Reaction Conditions:
with hydrazine in ethanol at 60; for 48 h;Inert atmosphere;Sealed tube;chemoselective reaction;
Steps:
2.1 General procedure of nitro compounds reduction by hydrazine catalyzed by Au/TiO2
General procedure: To a sealed tube containing the nitro compound (0.6 mmol) and 2 mL ethanol were added 2.6-6.0 mmol of NH2NH2 (see Table 2) and Au/TiO2 (100 mg, 1 wt.% in [Au], 0.8 mol%). The reaction was heated at 60 °C for an appropriate time (see Table 2) under an inert atmosphere. The reaction was monitored by TLC, and after completion, the slurry was filtered under pressure through a short pad of celite and silica gel to withhold the supported catalyst with the aid of ethanol or methanol (~ 5 mL). The filtrate was evaporated under vacuum to afford the corresponding amines in pure form. The spectroscopic data (1H NMR, 13C NMR) of amines 1a-20a are in agreement with those previously reported [28,30,31], while the majority of them are commercially available substances. The screened catalysts Au/TiO2, Au/Al2O3, and Au/ZnO (~ 1 wt.% in Au) are commercially available (Strem Chemicals), and have an average gold crystallite size of ~ 2-3 nm.
