Abstract

Abstract-The photosensitized reduction of some 4-nitrosopyrazoles and 4-nitrosoimidazoles using titanium dioxide as a photocatalyst has been investigated. The photoreaction produces the corresponding 4-aminoazoles and assumes an initial electron transfer from the conduction band of the excited titanium dioxide to the nitroso compound, followed by hydrogen transfer from the solvent. The photoreduction reaction takes also place by ...
