ine and N-benzyl-4-(3,5-dimethyl-1H-pyrazol-1-yl)-6-(piperidin-1-yl)-1,3,5-triazin-2-amine ) was studied and the molecularstructures were optimized using the DFT/B3LYP method. The structures were found to be in agreement with X-ray structures. The antimicrobial and antifungal activity of the prepared compounds were tested against the growth of several microorganisms.

preparation of the target compounds with excellent yields and good purities. The synthesized compounds were well characterized by NMR (1H and 13C), HRMS, and elemental analysis. Furthermore, the tautomerism of enhydrazine versus hydrazone has also been studied.

We herein report a new small library of Schiff-base compounds that encompasses s-triazine and (2 or 4)-hydroxylbenzylidene derivatives. These compounds were synthesized through a hydrazone linkage connecting both the s-triazine and hydroxybenzylidene derivatives. The synthetic strategy adopted allowed the synthesis of the target compounds with excellent yields and purities as observed from their NMR

The individual steps in the reactions of cyanuric chloride with n-butyl amine in N-methyl pyrrolidone (NMP) and with morpholine in isopropanol (i-PrOH) were followed kinetically. The ratio of the exchange rates of the first, the second and the third chlorine atom was unexpectedly high in both cases. The reactions of n-butylamino dichlorotriazine with several amines were studied kinetically both in NMP and in i-PrOH. Linear free-energy relationships exist both between our values in NMP and in isopropanol and between our values and reaction rates of p-nitro fluorobenzene with the corresponding amines (in DMSO) determined by Suhr.
