RISA Convenient Synthesis of Azobenzo-Crown Ethers
Azobenzo-Crown Ether with 10-16 ring size were synthesized...
Synthesis and application of new Schiff base Mn(III) complexes containing crown ether rings as catalysts for oxidation of cyclohexene and cyclooctene by Oxone
Six catalysts MnClL1–MnClL6, containing two crown ether rings, were synthesised and characterised by IR spectroscopy and CHN microanalysis. A combination of Oxone, as oxidant, and these catalysts was used for the oxidation of cyclohexene...
Microwave-assisted fast and efficient synthesis of some crown ethers
13-Crown-4, 16-crown-5, dibenzo-12-crown-4 and dibenzo-14-crown-4 were synthesized by a one-pot microwave-assisted
procedure in good yields. Irradiation of diols and dichlorides in the presence of sodium hydroxide in DMSO gave title crown...
spectrophotometric study of complex eormation of Y, La, andCe with some 18-and15-membered crown ethers in methanol
Complexation of some rare elements with 18C18C6,DEC18C6,B18C66,and B15C5 has been studied in methanol by spectrophotometry.

Synthesis and Biological Evaluation of Some New Thioether-Ester Crown Ethers
New thioether-ester crown ethers have been synthesized starting from oxalyl chloride and different β,β\\'-dihydroxydithioethers. The synthesized compounds are screened for their antibacterial activity. Among the macrocyclic thioether-esters (5a...
voltammetric determination of 4-nitrophenol using a modified carbon electrode based a new synthetic crown ether/silver nanoparticle
the analysis of phenols and substituted phenols in natural waters and effluents is of prime importance for enviromnetal control due the their appearance from wide range of activities.
Synthesis and Complexing Properties of Novel Crown Ethers and Thiacrown Ethers Incorporating New Heterocyclic Moieties
. The complexing ability of compounds
5b and 5h, as the representatives of both groups of compounds, with alkali and alkali earth
metal cations were measured by the solvent extraction method. The results showed that
crown ether 5b comparatively...
Efficient Synthesis of Macrocyclic Dilactam Crown Ethers by Fast Addition Method
A simple and convenient method for preparing macrocyclic dilactam crown ethers containing N2O5, N3O3, N3O4, N3O5 and N2O10 donor atoms with 18-32 membered rings was developed. These compounds were obtained in the macrocyclization step under vigorous...
Synthesis, biological evaluation and QSAR studies of some new thioether-ester crown ethers
New thioether-ester crown ethers have been synthesized starting from dithiodibenzoyl chloride and different β,β -dihydroxydithioethers. The synthetic compounds were screened for their antibacterial and antifungal activity on Klebsiella pneumoniae...
