Abstract
The aerobic oxidative coupling of aniline is an effective process for producing aromatic azo compounds, which are widely used in the organic chemical industry. The development of heterogeneous catalysts for this reaction would be advantageous because of their recyclability and convenience in posttreatment. In this work, one-dimensional Mn(OH)2 nanostructure with various shapes were synthesized through the adjustment of various surfactants. The as-synthesized Mn(OH)2 nanobelts and nanowires showed superior catalytic activity in the activation of oxygen and aniline. Aromatic azo compounds with a variety of substituents were produced through the coupling of the corresponding anilines without additives under ambient conditions.

- 37 Mn(OH)2 Nanobelts; Typical Procedure Mn(acac)3 powder (100 mg) was added to a 10 mL autoclave containing oleylamine (9 mL) with agitation. The clear solution was sealed into the autoclave and hydrothermally treated at 180 °C for 18 h, then cooled to r.t. The product was washed with EtOH (3 × 25 mL) then dispersed in cyclohexane (10 mL).
- 38 Azobenzene (1b); Typical Procedure A glass reactor was charged with aniline (1a; 0.5 mmol), Mn(OH2) nanobelts (50 mg), and p-xylene (50 mL) under O2 (1 bar), and the mixture was vigorously stirred at 140 °C for 16 h. The reaction system was then cooled to r.t., and the catalyst was separated from the mixture by centrifugation. The conversion was determined by GC. The supernatant was purified by flash chromatography on a short silica gel (eluent: petroluem ester) to give an orange solid; yield: 88%, 40 mg. 1H NMR (400 MHz, CDCl3, TMS): δ = 7.93–7.92 (d, 4 H), 7.54–7.46 (m, 6 H).13C NMR (100 MHz, CDCl3): δ = 152.66, 130.99, 129.09, 122.84.
