Reactivity of Tetramethylphosphonium Fluoride in Acetonitrile Solutions
Anhydrous tetramethylphosphonium fluoride dissolved in acetonitrile reacts slowly with the solvent under formation of (E)-2-amino-1-cyano-propene which was characterized by infrared and NMR spectroscopy. An attempted preparation of [Me3PF3]− by addition of Me3PF2 to Me4PF/acetonitrile solutions has shown that the desired reaction does not occur, but prolonged reaction times and small acetonitri...
متن کاملEncapsulation of charge-diffuse peralkylated onium cations in the cavity of cucurbit[7]uril.
Cucurbit[7]uril binds, with considerable size selectivity, NR(4)(+), PR(4)(+), and SR(3)(+) cations (R=Me, Et, (n)Pr, (n)Bu), with the smaller guests inside its cavity, rather than at the carbonyl-lined portals.
متن کاملInduced circular dichroism of polyoxometalates via electrostatic encapsulation with chiral organic cations.
To explore the principle of chiral induction in inorganic clusters, chiral organic cations with two stereocenters, R- and S-BPEA, are used to encapsulate a series of polyoxometalates (POMs) bearing different structures and transition absorption bands in aqueous solution, constructing a series of chiral supramolecular complexes. Due to the induction of chiral organic cations, POMs possessing bot...
متن کاملConformations of Internal Cyclopropylcarbinyl Cations (Benzobicyclo[ 4.1 .O]heptyl Cations) and Their Rearrangements to Naphthalenium Cations
Ionizations of 2-substituted l,l-dimethyl-3,4-methano-1,2,3,4-tetrahydronaphthalen-2-ols (8) (3,3-dimethylbenzobicyclo[4.1 .O]heptan-2-ols) in FS03H/S02CIF at -1 30 O C do not yield the corresponding 2-cations but benzylic (4-) cations 10 as a result of cyclopropylcarbinyl~yclopropylcarbinyl rearrangements. At higher temperatures, 10a and 10b undergo a further series of rearrangements to yield ...
متن کاملHermetic Encapsulation
‘Hermetic sealing’ is defined by the Shorter OED as “air-tight closure of a vessel by fusion, soldering or welding”. The term ‘hermetic package’ used in the electronics industry is however at best slightly misleading, in that the term is used to describe components where the die and associated bonds are sealed within a cavity in a hollow package (as distinct from being embedded in a resin), and...
