Synthesis and Characterization of Novel Schiff Base Macrocyclic Compounds Containing Thiophene

Chemical Research in Chinese Universities 2014年第3期30卷 383-386页

作者： DONG Xin LI Yuan gou xiaofeng ZHAO Junlong HUA Chengwen Key Laboratory of Synthetic and Natural Functional Molecule Chemistry Ministry of Education College of Chemistry and Materials Science Northwest University Xi' an 710069 P. R. China

Several novel Schiff base macrocyclic compounds containing thiophene were synthesized from d/ethyl 3,4-dialkoxythiophene-2,5-dicarboxylate, cyanuric chloride, diethylarnine and p-nitrophenol by reduction, oxidation, substitution and cyclization, and their structures were characterized by IR, NMR and electrospray ionization-rnass spectrorneter（ESI-MS）. The studies on their UV-Vis absorption spectra show that Schiff base rnacrocycles 6-10 have selective recognition for Fe^3＋.

Iron(Ⅲ) phthalocyanine chloride-catalyzed oxidation–aromatization of α,β-unsaturated ketones with hydrazine hydrate: Synthesis of 3,5-disubstituted 1H-pyrazoles

引用

Chinese Journal of Catalysis 2016年第4期37卷 571-578页

We have developed an iron（III） phthalocyanine chloride‐catalyzed oxidation–aromatization ofα,β‐unsaturated ketones with hydrazine hydrate. Various 3,5‐disubstituted 1H‐pyrazoles were obtained in good to excellent yields. This method offers several advantages, including room‐tem‐perature conditions, short reaction time, high yields, simple work‐up procedure, and use of air as an oxidant. The catalyst can be recovered and reused five times without loss of activity.
