Abstract

The title compound, N-(2-phenoxy-4-(3-phenoxyprop-1-ynyl)phenyl) methanesulfonamide was synthesized in high yield by Sonogashira cross coupling of N-(4-iodo-2-phenoxyphenyl)methanesulfonamide with 3-phenoxyprop-1-yne. The structure of the compound was fully characterized by IR, ¹H and ¹³C NMR, Mass spectra and elemental analysis. Full article

Abstract

Novel 4-[(2-hydroxy-4-pentadecylbenzylidene)amino]-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one was prepared via condensation of 2-hydroxy-4-pentadecylbenzaldehyde (1) with 4-amino-1,2-dihydro-2,3-dimethyl-1-phenylpyrazol-5-one (2) in ethanol/acetic acid under reflux. The structure of the synthesized compound was assigned on the basis of elemental analysis and spectral data. Full article
