Application

Cetyltrimethylammonium hydrogensulfate is commonly used as a surfactant for organic transformation in the aqueous medium.
Some of the applications include:
  • Rhodium(I)-catalyzed asymmetric hydrogenation of (Z)-methyl-α-acetamidocinnamate.
  • Asymmetric palladium-catalyzed alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate.

Photocatalytic reduction of aqueous Cr(VI) was successfully achieved on nanostructured SnIn(4)S(8). The SnIn(4)S(8) particles with flower-like nanostructure were synthesized via a facile solvothermal method. UV-vis diffuse reflectance spectra (DRS) indicated that the SnIn(4)S(8) particles had strong absorption in visible region
