Bradshaw The Chemistry of Heterocyclic Compounds, Aza-Crown Macrocycles. A series of new chiral macrocycles containing the trans-1,2-diaminocyclohexane (DACH) subunit and arene- and oligoethylene glycol-derived spacers has been prepared in enantiomerically pure form.
Four of the macrocycles have been characterized by X-ray crystallography, which reveals a consistent mode of intramolecular N–HN hydrogen bonding and conformational variations about the N Cited by: The novel bibrachial lariat ethers (BiBLEs) 3a-d with neutral side chains were preparedby reaction of the corresponding aza-crown macrocycles 1a-b with ethyl chloroacetate and chloroacetamide.
macrocycles due to their larger cavity size compared to the membered cycles. The structures of macrocycles were confirmed by CHN/O analysis, IR, 1H NMR, 13C NMR and mass spectrometry.

Journals & Books; Help in L 1 and L 3 tweezers was a reversible process in terms of the chemical shift of the aromatic protons on the aza-crown macrocycles.
The calculated association constants by UV–vis spectroscopy revealed that C 60 interacted with the L 1 and L 3 more strongly in the presence than in the absence of the UV by: 2.
The linker was made from aza-crown macrocycle bearing two pyridine moieties. The TGA exhibited thermal stability up to °C. The complex showed strong performance as Sonogashira cross-coupling catalyst. The catalyst was moisture/air-stable, copper and phosphine by: 6. Ruthenium(II) complexes of some new polynucleating ligands incorporating terpyridyl and macrocyclic aza-crown binding sites - Journal of the Chemical Society, Dalton Transactions (RSC Publishing) A series of five new compounds has been prepared in which terpyridyl fragments are linked to hexadentate aza-crown by: Electrospray ionization mass spectrometry (ESI-MS) is used to evaluate the metal binding selectivities of an array of novel caged macrocycles for silver, gold, copper, nickel, zinc, iron, lead, manganese and alkali metal ions.
It is found that five of the new compounds display silver selectivity, and their rCited by: Crown ethers are cyclic chemical compounds that consist of a ring containing several ether groups. The most common crown ethers are cyclic oligomers of ethylene oxide, the repeating unit being ethyleneoxy, i.e., –CH 2 CH 2 O–.
