The hydration of alkali cations yields a variety of structural conformers with varying numbers of water molecules in the first solvation shell. How these ions move from the aqueous phase into biological systems, such as at the entrance of an ion channel, depends on the interplay between competing intermolecular forces, which first must involve ion-water and water-water interactions. New infrared action spectra, using argon as a messenger or "spy", for Li(+), Na(+), and K(+), with up to five water molecules are reported, and new structural conformers determined from ab initio calculations, combined with previous results on Rb(+) and Cs(+), have identified structural transitions at each hydration level. These transitions are a result of the delicate balance between competing noncovalent interactions and represent a quantitative microscopic view of the macroscopic enthalpy-entropy competition between energy and structural variety. Smaller cations (Li(+) and Na(+)), with higher charge density, yield structural configurations with extended linear networks of hydrogen bonds. Larger cations (Rb(+) and Cs(+)), with lower charge density, generate configurations with cyclic hydrogen-bonded water subunits. It appears that K(+) is somewhat unique, with very simple (and predominantly) single structural conformers. This has led to the suggestion that K(+) can "move" easily in or through biological systems, concealing its identity as an ion, under the "appearance" or disguise of a water molecule.

“…Cesium fluoride (CsF) has emerged as an efficient, mild and basic catalyst used as a source of the fluoride ion in organic chemistry [30]. The synthetic approaches using CsF are found in rapid and efficient Knoevenagel-Michael condensation reactions [31] since the high affinity of CsF makes it capable of binding with the aldehyde carbonyl oxygen, thus increasing the reactivity of the parent carbonyl compounds.…”

Selective Conversion of Carbon Dioxide to Formaldehyde via a Bis(silyl)acetal: Incorporation of Isotopically Labeled C₁ Moieties Derived from Carbon Dioxide into Organic Molecules

The conversion of carbon dioxide to formaldehyde is a transformation that is of considerable significance in view of the fact that formaldehyde is a widely used chemical, but this conversion is challenging because CO2 is resistant to chemical transformations. Therefore, we report here that formaldehyde can be readily obtained from CO2 at room temperature via the bis(silyl)acetal, H2C(OSiPh3)2. Specifically, formaldehyde is released from H2C(OSiPh3)2 upon treatment with CsF at room temperature. H2C(OSiPh3)2 thus serves as a formaldehyde surrogate and provides a means to incorporate CH x (x = 1 or 2) moieties into organic molecules. Isotopologues of H2C(OSiPh3)2 may also be synthesized, thereby providing a convenient means to use CO2 as a source of isotopic labels in organic molecules.
