Abstract

Abstract Preyssler-type heteropolyacid supported on TiO 2 nanoparticles has been explored as an efficient catalyst in selective oxidation of primary aromatic amines to azoxy derivatives using trans-3, 5-dihydroperoxy-3, 5-dimethyl-1, 2-dioxolane as oxidant. The reactions proceeded smoothly under mild and green ultrasound-accelerated conditions to afford the products in high yields. The catalyst recovered from the reaction mixture exhibits long-term ...
