A Cooperative Catalytic System of Platinum/Iridium Alloyed Nanoclusters and a Dimeric Catechol Derivative: An Efficient Synthesis of Quinazolines Through a Sequential Aerobic Oxidative Process

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 conditions highlights the synthetic application of this cooperative catalytic system.
