Synthesis of Merocyanine Dyes
View through CrossRef
Abstract
New 1-ethyl-2-[(2-substituted 3-oxoisoindolin-1-ylidene)methyl]-pyridinium or quinolinium iodide merocyanine dyes were obtained by the reaction of 2-methyl quaternary salts with N-substituted phthalimide in the presence of piperidine. 1-Ethyl-2-[(1-substituted 5-oxo-3-pyrrolin-2-ylidene)methyl] quinolinium iodide merocyanines were also prepared. Structural configuration of the synthesised compounds was confirmed by IR and UV spectral determination. 1-Ethyl-2-[[3-oxo-2-(4-phenylthiazol-2-yl)isoindolin-1-ylidene]methyl]quinolinium iodide has high bactericidal activity againsist E.Coli, Staphylococcus Aureus, and Staphylococcus Albas.
