Amino functionalized triazine supported on silica-gel was prepared and characterized. This new triazine derivative was applied as a coordinating agent for aluminum chloride. This novel Lewis acid supported on heterogeneous surface was used as an effective catalyst for protection of alcohols and phenols in the presence of 3,4-dihydro-2H-pyran. This catalyst can be reused without any significant loss of activity, and it protects alcohols in the presence of phenols.

Amino-functionalized triazine supported on silica-gel was prepared. is new triazine derivate was applied as a coordinating agent for copper (II) and was characterized by different methods. e copper (II) content of the material was determined by atomic absorption. is novel transition metal supported on heterogeneous surface was used as an effective catalyst for oxidation of benzylic alcohols in the presence of H 2 O 2 . is catalyst can be reused without any signi�cant loss of activity.

A new approach to the synthesis of new heterocyclic compounds with benzoylisothiocyanate, amines, and 2‐bromoacetophenone (phenacyl bromide) fragments in one molecule has been developed. The synthesis method comprises condensation reaction for the preparation of novel (4‐phenylthiazol‐2(3H)‐ylidene) benzamide derivatives. These new compounds were synthesized via one‐pot and multicomponent reaction of 2‐furanmethylamine, 5‐chloro‐2‐phenoxyaniline, and 1‐naphthylamine with phenacyl bromide and substituted benzoylisothiocyanates. Moreover, new series of anthraquinone‐thiazole hybrids have been synthesized. These compounds were prepared from unsymmetrical thiourea containing anthraquinone and dialkyl acetylenedicarboxylate. The nature of the compounds was confirmed by IR, 1HNMR, 13CNMR, mass spectrometry, and CHNS elemental analysis. The structural elucidation was accomplished by single‐crystal X‐ray diffraction methods.
