Rearrangement of 1,3-bis(azacrown)-2-chloropropanes: the effect of alkali metal ion on neighbouring group participation

Martin Bělohradský; Petr Holý; Juraj Koudelka; Viktor Krchňák; Jiří Závada

A pronounced effect of alkali metal ion on rate and product distribution has been found in the reaction of the twelve-, fifteen- and eighteen-membered 1,3-bis(azacrown)-2-chloropropanes 1a–c with benzyl oxide–benzyl alcohol base–solvent system.


Journal of The Chemical Society, Chemical Communications | 1990

A new type of functionalized cryptand-like ionophore. Synthesis, structure and complexation

Ivan Stibor; Petr Holý; Jiří Závada; Juraj Koudelka; Jaromir Novák; Jaroslav Zajíček; Martin Bělohradský

New functionalized cryptand-like ionophores are prepared from appropriate diaza-crown ethers and epichlorohydrin, using FAB MS, potentiometry, 13C-NMR spectroscopy, and T1 relaxation times measurements, the conformation and complexation patterns are found to change dramatically with the change in size of the macrocycle.
