Nuclear Magnetic Resonance Studies of Substituted s-Triazines in Solution

Abstract

Substituted <i>s</i>-triazines are biologically active compounds and are commonly used as herbicides. The proton magnetic resonance (PMR) spectra of several 2, 4 substituted triazines has been reported by Declerck <i>et al.</i> The <i>s</i>-triazine herbicides described by the general formula (I) are readily adsorbed on surfaces and are protonated when (R<sub>1</sub>, R<sub>2</sub>, R<sub>3</sub>, or R<sub>4</sub> are alkyl group or H); (Y=Cl, OCH<sub>3</sub>, or SCH<sub>3</sub>) an acidic proton is available on the [Equation 1] surface. In this paper we shall present the PMR spectra of several <i>s</i>-triazines. Studies have also been carried to investigate the PMR spectra of these compounds in a strongly protonating trifluoro acetic acid (TFA) as solvent.
