Continuous-flow hydrogenation of aromatic nitro compounds was successfully performed by using polysilane-supported palladium catalysts to afford the corresponding amino compounds in high yields. Productivity was high, and a wide variety of nitro compounds were applicable under the continuous-flow conditions. It is noted that no leaching of palladium was observed by inductively coupled plasma analysis.
A complex of Fe(III) with 1,2 dihydroxy 9, 10, anthraquinone (DHA) has been prepared. The metal ion forms a 13 complex with DHA. The complex is formed due to the dissociation of one proton per ligand bound to the metal ion. The stability constant of the Fe(III) complex is 1.61·1032. The complex reduces the catalytic flow of electrons from NADH to molecular O2 through NADH dehydrogenase over DHA. The Fe(III) compelx is seen to be an efficient radiosensitizer towards -radiation induced degradation of thymine in a nitrous oxide saturated medium.
