Phenol as a modulator in the chemical reactivity of 2,4,6-Trichloro-1,3,5-triazine: Rules of the Game II

Abstract:

2,4,6-Trichloro-1,3,5-triazine (TCT) is a privileged core that has the capacity to undergo sequential nucleophilic substitution reactions. Three nucleophiles, namely phenol, thiol and amine, were studied and the preferential order of incorporation on TCT was found to be first phenol, second thiol and third amine. The introduction of phenol was achieved at -20°C. The incorporation of this nucleophile in TCT helped to replace the third 'Cl' at 35°C, which is compatible with a biological context. The atomic charges on 'Cl' calculated by theoretical approaches were consistent with the experimental findings.
