Ultra Violet Spectra of N-Hydroxy Amidines
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2019, Vol 12, Issue 1
Abstract
Hydroxyamide Hydrochloride was prepared by condensation of N (4- Fluoro) benzamidoyl chloride and N- phenyl hydroxylamine at 00 -5 0C in ether medium. White crystals of N-HydroxyN- phenyl benzamidine hydrochloride were separated. They were separated and recrystallized from absolute alcohol. The newly synthesized reagent was characterised on the basis of melting point, elemental analysis and ultra violet spectra. The molecular formula C19H16 N2OFCl is confirmed from elemental analysis data. The ultra violet absorption spectra of hydroxyamidine in ethanol show three distinct absorption band attributed to π-π* transitions. The band observed around 207nm has been assigned as local excitation band of phenyl chromophore and the other two bands around 250-260 nm and 300-322 nm have been assigned as electron transfer band. Electron transfer band are sensitive to substitution in the aromatic system of compound.
