HKUST-1 Metal Organic Framework as an Efficient Dual-Function Catalyst: Aziridination and One-Pot Ring-Opening Transformation for Formation of β-Aryl Sulfonamides with C-C, C-N, C-S, and C-O Bonds

Autor: Sajan Pradhan, Debesh Sharma, Anand Pariyar, Khanindram Baruah, Sagarmani Rasaily, Sudarsan Tamang

Publikováno v: Inorganic chemistry. 60(11)

Metal-organic frameworks (MOFs) are extensively used in catalysis due to their robust structure, well-defined periodic reaction centers, and high porosity. We report Cu3(BTC)2·(H2O)3 (HKUST-1) as an efficient heterogeneous catalyst for aziridination
