呋喃查尔酮紫外光谱的取代基效应
SUBSTITUENT EFFECT ON THE UV SPECTRA OF FURAN CHLCONES
【Abstract】 Five furan chalcones were synthesized by condensation of α acetofuranone with aromatic aldehydes in the presence of KF Al 2O 3.The UV Spectra of compounds 3(a~e)in sixteen solvents have been measured.Linear relationship between V uv max and σ + p is obtained.
