Iron chemistry of an asymmetrically substituted, triazole-functionalised calixarene ligand
Ritter, Michaela,Molad, Anat,Rawat, Varun,Vigalok, Arkadi,Limberg, Christian
, p. 530 - 537 (2014/07/08)
The synthesis and characterisation of an asymmetrically substituted calix-triazole ligand are reported. The ligand reacts with the Fe(II) precursor Fe2Mes4 to yield an iron(II) calixarene complex that is oxidised by dioxygen to provi

Zhao, Bing,Ruan, Yao-Yu,Deng, Qi-Gang,Wang, Li-Yan,Song, Bo,Feng, Ya-Qing
, p. 19 - 22 (2013/06/04)
A series of 2-pyridylthio and 2-pyrimidinylthio derivatives of calix[4]arene have been synthesized and characterized by IR, 1H NMR, 13C NMR and MS.
Microwave-assisted synthesis of 1,3-dialkyl ethers of calix[4]arenes: Application to the synthesis of cesium selective calix[4]crown-6 ionophores
Nayak, Sandip K.,Choudhary, Manoj K.
supporting information; experimental part, p. 141 - 144 (2012/01/17)
Partial etherification of phenolic-OH groups of calix[4]arenes with various alkyl halides/tosylates and K2CO3 under microwave irradiation afforded 1,3-dialkoxycalix[4]arenes in their cone conformation only as predominant/sole product
Easy and selective method for the synthesis of Mono-, di-, tri-, tetra-O-arylmethyl-p-t-butylcalix[4]arenes
Xie, Yuanyuan,Xia, Wang
experimental part, p. 402 - 406 (2012/09/21)
Mono-, di-, tri- and tetra-O-arylmethyl-p-t-butylcalix[4]arenes were synthesised respectively from p-t-butylcalix[4]arene and arylmethyl bromide through an easy and selective one-step reaction. Mono- and di-arylmethyl ethers of p-t-butylcalix[4]arenes wer
Evaluation of calix[4]arene-based chiral diphosphite ligands in Rh-catalyzed asymmetric hydrogenation of simple dehydroamino acid derivatives
Liu, Shasha,Sandoval, Christian A.
scheme or table, p. 65 - 72 (2010/09/05)
The versatile calix[4]arene framework yielded chiral diphosphite ligands applicable for Rh-catalyzed asymmetric hydrogenation of dehydroamino acid derivatives. Optimum efficiency was obtained for: R1 =-C(CH 3)3; R2/s
Calix[4]arene-dithiacrown ethers: synthesis and potentiometric membrane sensing of Hg2+
Yang, Yanfei,Cao, Xiaodan,Surowiec, Malgorzata,Bartsch, Richard A.
experimental part, p. 447 - 454 (2010/03/03)
A series of calix[4]arene-dithiacrown-5 and -dithiacrown-6 compounds in cone and 1,3-alternate conformations has been synthesized. Responses of these ionophores to Hg2+ and competing metal ions were determined in solvent polymeric membrane electrodes. High potentiometric selectivity for Hg2+ over Na+ and a variety of transition and heavy metal ions was obtained.
Wide- and narrow-rim functionalised calix[4]arenes: synthesis and characterisation
Creaven, Bernadette S.,Gernon, Tammy L.,McGinley, John,Moore, Ann-Marie,Toftlund, Hans
, p. 9066 - 9071 (2007/10/03)
Functionalisation of calix[4]arene at both the wide and narrow rims leads to the formation of compounds containing bipyridyl, via an amide linkage, at the wide rim and having either a butyl chain, a benzyl group or an alkyl ester functionality at the narrow rim. All compounds were characterised using 1H and 13C NMR spectroscopies. Initial binding studies with Ru(bipy)2Cl2 are reported.
Membrane extraction of organic compounds 3. A new receptor fragment for carboxylate groups based of the calix[4]arene platform
Antipin,Stoikov,Khrustalev,Konovalov
, p. 2134 - 2143 (2007/10/03)
A new type of macrocyclic receptor able to bind organic substrates containing carboxy and carboxylate groups was designed on the basis of 1,3-disubstituted calix[4]arenes. A series of disubstitited calix[4]arenes were prepared in 60-80% yields by selectiv
