Abstract

Abstract A cooperative catalytic system of heterogeneous polymer-supported bi-metallic platinum/iridium (Pt/Ir) alloyed nanoclusters and 5, 5′, 6, 6′-tetrahydroxy-3, 3, 3′, 3′- tetramethyl-1, 1′-spiro-bisindane (TTSBI) enabled the facile preparation of quinazoline derivatives with low catalyst loadings and broad substrate scope under mild aerobic oxidative conditions. The ability to perform the reaction in gram-scale and under open-air ...
