Superalkali-Alkalide Interactions and Ion Pairing in Low-Polarity Solvents

The nature of anionic alkali metals in solution is traditionally thought to be "gaslike"and unperturbed. In contrast to this noninteracting picture, we present experimental and computational data herein that support ion pairing in alkalide solutions. Concentration dependent ionic conductivity, dielectric spectroscopy, and neutron scattering results are consistent with the presence of superalkali-alkalide ion pairs in solution, whose stability and properties have been further investigated by DFT calculations. Our temperature dependent alkali metal NMR measurements reveal that the dynamics of the alkalide species is both reversible and thermally activated suggesting a complicated exchange process for the ion paired species. The results of this study go beyond a picture of alkalides being a "gaslike"anion in solution and highlight the significance of the interaction of the alkalide with its complex countercation (superalkali).

An efficient route to symmetrically and unsymmetrically substituted azamacrocyclic ligands

An extremely efficient cyclisation protocol has been developed for the synthesis of symmetrically (6) and unsymmetrically substituted (7) derivatives of 1,4,7-triazacyclononane (2). The optimised conditions can be successfully applied to the synthesis of larger macrocycles 15a and 18a. In contrast, the protocol is not generally applicable with benzylamine, and the cyclic carbamates 16 and 19, rather than larger azamacrocycles, are formed, indicating that cyclisation in CH3CN using K2CO3 is highly specific to the formation of 7.
