چکیده

an efficient method has been developed for the catalysis of condensation of 1,2-phenylenediamines and 2-aminothiophenoles with different aldehydes into their corresponding 2-aryl-1h-benzimidazoles and 2-aryl-1h-benzothiazoles under mild condition. in this method, trans-3,5-dihydroperoxy-3,5-dimethyl-1,2-dioxolane (dhpdmdo)/hoac/ki system was used as a novel and effective oxidant in water at room temperature with excellent results.

Nano-CrY zeolite as a new and reusable catalyst for synthesis 2-aryl-1H-benzothiazoles

The Nano-CrY zeolite synthesized and characterized by Fourier transfer infrared (FT-IR), X-ray diffraction (XRD),and Scanning electron microscopy (SEM).The result show that nano catalyst prepared with mainly particles size about 30-80 nm .The XRD show the structure of the zeolite does not collapse. This Nano-CrY zeolite has been used as new, and nontoxic catalyst for catalyzes of synthesis of 2...
