Bu çalışmada, 5,17-bis-tert-butil-11,23-dikarboksilik asit-25,27-dihidroksi- 26,28-bis(3-tiyol-1-oksipropan)-kaliks[4]aren (5) bileşiği başarıyla sentezlenmiştir. Sentezlenen bileşiğin yapısı 1HNMR, 13CNMR ve elementel analiz teknikleri kullanılarak aydınlatılmıştır. Elde edilen merkapto grubu bağlı kaliks[4]aren türevi, yeni bir polimer içerikli membran hazırlanması için selüloz triasetat 2-ni...

This work is concerned with the preparation of a number organic ammonium formate salts (or ionic liquids; ILs) throughout reaction between formic acid and some aliphatic aromatic amines including ammonia. Five were formed, them in form solid others as liquids (ILs) at room temperature. The yields prepared ranged from (21%) to (79%). However, attempts towards other fifteen not successful. result...

In this work, magnetic mesoporous silica-alumina composites (MSA) containing three metal oxides(MSA/MO) with different molar ratio of Si to Al (0.5, 1 and 2) were synthesized. The efficiency prepared catalysts was compared modified natural zeolite (ferrierite) in the multicomponent synthesis indeno[1,2-b]indole-9,10-diones. Immobilization ZnO, CuO NiO on increased their Lewis acidic sites impro...

Abstract Diphenylamine (DPA), formyl chloride, and sodium hydride (NaH) as raw materials synthesize methyldiphenylurea stabilizer by alkylation reaction. The physical chemical properties of were characterized nuclear magnetic resonance hydrogen spectrum (1HNMR), X-ray energy (EDS), Fourier transforms infrared spectroscopy (FT-IR) differential thermal analysis (DTA). Thermal Decomposition Experi...

The present work deals with the sequence of Novel Pyrazole fused Indole derivatives(4a-4l) were synthesized by simple conventional method andscreened for anthelmintic, antibacterial and anticancer activities. molecular docking studies also performed. All newly synthesizedcompounds structurally characterized on basis IR, 1HNMR Mass spectral analysis. Further, all prepared pyrazole fusedindole de...

Utilization of benzoxazinone for synthesis quinazolinone derivatives with 3-heterocycle side chain. treatment of benzoxazinon 1 with cyano acetohydrazide or thionocarbohydrazide gave the quinazolinone derivatives 2 or 12. quinazolinone 2 has been utilized as synthon for new  pyridinone, oxazet, thiazole, thiazolidinone and quinazolinone derivatives. Thiosemicarbazide and thiosemicarbazone deriv...

The characterization and design of this study new liquid crystals with a V shape compounds containing thiazolidine-2,4-dione 1,3-phenylene as core unite mesophase properties were reported. Preparation chloroacetic acid, water, thiourea to produce [I] in the presence strong hydrochloric acid. 4-hydreoxybenzaldehyde n-alkyl bromide reacted potassium hydroxide create n-alkoxy benzaldehyde., then c...
