Synthesis of Tetraketones Using ZnS Nanoparticles as an Efficient Catalyst

An efficient pseudo‐three‐component synthesis of tetraketones is described by one‐pot condensation of 5,5‐dimethylcyclohexane‐1,3‐dione and aldehydes using ZnS nanoparticles at room temperature. This method provides several advantages such as mild reaction conditions, applicability to a wide range of substrates, reusability of the catalyst, and low catalyst loading.
