Niꢀcomplexꢀboehmite I (0.004 g, 0.27 × 10ꢀ3 mol%) or Niꢀcomplexꢀ
boehmite II (0.008 g, 0.29 × 10ꢀ3 mol%) was added to a mixture of
thiol (1 mmol) and H2O2 (0.4 mL) in ethanol (3 mL). Then the
mixture was stirred for the appropriate time at room temperature. 12. F. Dehghani, A.R. Sardarian, M. Esmaeilpour, J. Organomet. Chem.
The progress of reaction was monitored by TLC. After completion
of the reaction, the catalyst was separated by filtration and the
mixture was washed with ethyl acetate. The product was extracted
with ethyl acetate. The organic layer was dried over anhydrous
Na2SO4 (1.5 g). The products were obtained in good to high yield.
