Abstract:

In this report, the synthesis, characterization, and application of the eggshell-supported-Cu(II) salophen complex, as a novel and heterogeneous catalyst, is described. The catalyst is characterized by the UV, XRD, FT-IR, and SEM techniques. The eggshell-supported-Cu(II) salophen complex is a versatile, green, inexpensive, and simple catalyst used for the multi-component reactions (MCRs) of terminal alkynes, aldehydes, and secondary amines to give the corresponding propargylamines at 80 °C under the solvent-free conditions. The proposed methodology offers several advantages such as excellent product yield, simple procedure, and mild conditions. On the other hand, the synthesized catalyst could be removed from the reaction mixture by simple filtration, and reused for up to six runs.

Natural Kaolin supported sulfuric acid as an efficient catalyst for the preparation of 1, 1-diacetates under solvent-free conditions

A facile and efficient method for the preparation of 1,1-diacetates of aldehydes is improved. The acidified kaolin with sulfuric acid (2 % w/w) catalyzed 1,1-diacetates formation from aldehydes in solvent-free conditions. Both aromatic and aliphatic aldehydes gave high yields (85-95 %) of the corresponding 1, 1-diacetates. Advantages of this method are the use of inexpensive and selective catal...
