Synthesis of novel tri-arm star shaped 1,3,5-triazine hydrazones from 2,4,6-tris(4-acetylphenoxy)-1,3,5-triazine Core

摘要

A series of novel symmetric triazine hydrazones [N _3C _3(-OC _6H _4-p-C(CH _3)=N-NH-C(O)-C _6H _4-p-X) _3] (X = H, Br, Cl, F, OH, OCH _3, CH _3, NO _2, NH _2) were prepared in excellent yields by a three-fold condensation reaction of 2,4,6-tris(4- acetylphenoxy)-1,3,5-triazine with p-substituted benzoic acid hydrazides [NH _2-NH-C(O)-C _6H _4-p-X]. The structures were confirmed by FT-IR, ~1H, ~(13)C, 2D-HMQC NMR and mass spectrometry (MALDI-TOF).
