SYNTHESIS AND PROPERTIES OF 3- AND 4-AMINOBENZYLAMINE DERIVATIVES

Kraska, Jan,Teodorczyk, Zygmunt

, p. 1025 - 1034 (2007/10/02)

Derivatives of 3- and 4-aminobenzylamine substituted by chlorine atom, methyl or methoxyl group in the ring position 2, 4, 5 or 6 were synthesized.Structures of the compounds obtained were confirmed by spectroscopic (IR, NMR) and physico-chemical methods. pKa values were determined for the prepared amines and correlated with ? constants of substituents.The values of ?n meta and ?n para were found for the methylammonium group.
