Chemistry of the Alkaline Earth Metal Enolates
Aldehydes, ketones, carboxylic esters, carboxylic amides, imines and N,N-disubstituted hydrazones react as electrophiles at their sp2-hybridized carbon atoms. These compounds also become nucleophiles, if they contain an H atom in the a-position relative to their C O or C N bonds. This is because they can undergo tautomerization to the corresponding enol as seen in Chapter 12. They are also C,H-...
متن کاملDansyl - Substituted Aza Crown Ethers: Complexation with Alkali, Alkaline Earth Metal Ions and Ammonium.
The present study investigates the binding properties of four dansyl substituted aza-crown ethers with alkali, alkaline earth metal ions and ammonium. The influence of the solvent polarity and protonation on the photophysical properties of the compounds was studied by UV/Vis and fluorescence methods. The host species caused only slight changes on the absorption spectra of the ligands. The fluor...
متن کاملQuantum computing with alkaline-Earth-metal atoms.
We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...
متن کاملDetermination of ammonium cations and alkali and alkaline earth metal cations in jellyfish by capillary zone electrophoresis.
We developed a capillary zone electrophoresis method with indirect UV detection for determination of ammonium cations and alkali and alkaline earth metal cations in jellyfish. As the background electrolyte, a mixture of N-methylbenzylamine, citrate, and 18-crown-6 was used for the complete separation of all analyte cations. The limits of detection were 0.13 - 0.34 mg l(-1) at a signal-to-noise ...
متن کاملOn Reduction of Ammonium Molybdate in Acid
Ammonium molybdate, in acid solution, is reduced to an oxide stage, with the production of a blue color, by many substances of biological importance. Our attention was first attracted to this subject through an accidental observation. We were engaged in the attempt to work out a technique for the nephelometric estimation of phosphoric acid, using a heavy solution of cane sugar for the medium of...
