Allgemeine Beschreibung

Cesium hydroxidemonohydrate is commonly used as a catalyst in many organic transformations andas an initiator in polymerization reactions.

Anwendung

Cesium hydroxide monohydrate can be used as a catalyst in the synthesis of:
  • O-allenes and N-allenes via isomerization of terminal alkynes. This method allows the efficient synthesis of allenes in high yields under mild conditions with wide functional group tolerance.
  • Unsymmetrical bis-allyl ethers consist of an E-allylic unit and a terminal allylic unit via dimerization of Baylis-Hillman adducts.
Cesium hydroxide monohydrate can also be used as an initiator for the heterogeneous ring-opening polymerization of monosubstituted oxiranes.

Electrolyte cations affect the activity of surface-mediated electrocatalytic reactions; however, understanding the modes of interaction between cations and reaction intermediates remains lacking. We show that larger alkali metal cations (excluding the thickness of the hydration shell) promote the electrochemical CO

(13)C metabolic MRI using hyperpolarized (13)C-bicarbonate enables preclinical detection of pH. To improve signal-to-noise ratio, experimental procedures were refined, and the influence of pH, buffer capacity, temperature, and field strength were investigated. Bicarbonate preparation was investigated. Bicarbonate was prepared and

Electrolysis is omnipresent in all electrochemical processes including electromembrane extraction (EME). The effects of electrolysis on quantitative aspects of EME were comprehensively evaluated for a set of acidic (substituted phenols) and basic (basic drugs) analytes. EMEs were carried out across

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.
