In this study, a simple one-pot synthesis of acetamides from aromatic amines and acetonitrile in the presence of H2O and K2S2O8 is presented. The reaction proceeds in a mixed solvent (CH3CN: DMSO, 3:1) without using metals or toxic reagents. Various N-acetanilides are obtained with 53-91% yields. The method is selective for aromatic amines, with aliphatic amines remaining intact. This represents a new, efficient, and ec Read More

Surfactants have great importance in biological and drug industries and the complexes of metallic soaps with various ligands are used in approximately every region of national economy. Therefore, our keen interest to study of degradation kinetics and biological importance of Cu (II) surfactants in non-aqueous and non-polar solvent benzene. Present research work has been initiated with synthesis, systematic study of Read More

Caffeoyl spermidines are valuable alkaloids naturally existing in many plant species. These alkaloids are characterized as pharmacologically important ingredients of many plant extracts used in traditional medicines. Bis-caffeoylspermidine and bis-dihydrocaffeoylspermidine exhibit antioxidant, anti-inflammatory, and enzyme inhibition properties that make them valuable natural sources of safer therapeutic agents.
