Dipole moment studies of some derivatives of 4-pyridone

open access: yesAustralian Journal of Chemistry, 1972
The dipole moments of 13 derivatives of 4-pyridone were measured. Attempts to obtain a value for 4-pyridone were unsuccessful but a value of 6.O D is compatible with other evidence. Dipole moment and n.m.r, evidence indicated that for N-phenyl-4-pyridone

Tautomerism of 4-Pyridones [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1977
Abstract The tautomeric constants, Kt, of several 4-pyridones were determined by measurement of pKa values. For 2-substituted 5-methoxy-4-pyridones, the Kt values were correlated to the substituent constants σ, the equation logkt=2.98+2.93σm−6.18σo being obtained.
