The development of efficient and environmentally friendly catalytic systems for making sulfur-containing heterocycles remains an important goal in synthetic chemistry. Here we describe a new hybrid nanocatalyst, Bis-GO@SiO2@[(CH2)3Im][Cl], that combines bis-functionalized graphene oxide, a silica coating, and an immobilized imidazolium-based ionic liquid. This material works as a highly active and recyclable platform for the multicomponent synthesis of 2-thioarylbenzoazoles. The method tolerates
