Conversion of Nitrosobenzene to Azoxybenzene Over a Cerium(IV) Oxide Photocatalyst Under Visible Light
Abstract Azoxybenzenes are of great importance in the field of liquid crystals and polymer materials. The results of this study showed that irradiation of visible light to nitrosobenzene in an alcohol suspension of cerium(IV) oxide (CeO 2 ) resulted in the selective production of azoxybenzene with a high yield. Reactions carried out under different conditions showed that the overall reaction consisted of two distinct reactions. The first reaction involved photoexcitation of CeO 2 , which reduced nitrosobenzene to N ‐phenylhydroxylamine and oxidized 2‐propanol to acetone. In the second reaction, N ‐phenylhydroxylamine and nitrosobenzene were condensed to azoxybenzene.
