New Nitrogen-Rich Tripodal Molecules Based On Bis(Pyrazol-1-Ylmethyl)Amines With Substituents Modulating Steric Hindrances And Electron Density Of Donor Sites

摘要

Eight new substituted bis(pyrazol-l-ylmethyl)amines have been prepared in one step condensation of l-(hydroxymethyl)-3,5-disubstituted pyrazoles with a series of primary amines. The effect of substituents of divers bulkiness and electron donor/acceptor power that have been introduced to these tridentate molecules is visualised by ~1H NMR spectroscopy.
