In this study, a highly active catalyst based on copper iodide nanoparticles supported on magnetic aminomethylpyridine functionalized cellulose has been synthesized and characterized. Its catalytic activity was investigated in the multicomponent synthesis of N-sulfonylamidines via an in situ generated sulfonyl ketenimine intermediate under solvent free conditions at room temperature The desired products were obtained in good to excellent yields at short reaction times. Based on observed results, the synthesized catalyst was an efficient, magnetically separable, recyclable and green catalyst from a natural source. In the experiment, the researchers used many compounds, for example, 1-(Phenylsulfonyl)piperazine (cas: 14172-55-5Application of 14172-55-5).
1-(Phenylsulfonyl)piperazine (cas: 14172-55-5) belongs to piperazine derivatives. Simple N-substituted piperazines have been found in many drug molecules. Two common salts in the form of which piperazine is usually prepared for pharmaceutical or veterinary purposes are the citrate, 3C4H10N2.2C6H8O7 (i.e. containing 3 molecules of piperazine to 2 molecules of citric acid), and the adipate, C4H10N2.C6H10O4 (containing 1 molecule each of piperazine and adipic acid).Application of 14172-55-5
