Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 250285-32-6, C27H37ClN2.

The direct regioselective allylation of in situ generated aldehyde acyl anions has been achieved by synergistic NHC and Pd catalysis. It provides an efficient access to valuable beta,gamma-unsaturated ketones under mild reaction conditions starting from easily accessible allylic carbonates and aldehydes without any preactivation. The synergistic catalysis method demonstrated herein adds a new dimension to the area of metal-mediated C allylation.

23190-16-1, Name is (1R,2S)-(−)-2-Amino-1,2-diphenylethanol, molecular formula is C6H5CH(NH2)CH(C6H5)OH, belongs to chiral-catalyst compound, is a common compound. In a patnet, once mentioned the new application about 23190-16-1, Formula: C6H5CH(NH2)CH(C6H5)OH

At 2.5 mol % loadings using reaction temperatures between 30-55 C, ortho-functionalized diaryl diselenides are highly effective organocatalytic oxidants for aerobic redox dehydrative amidic and peptidic bond formation using triethyl phosphite as a simple terminal reductant. This simple-to-perform organocatalytic reaction relies on the ability of selenols to react directly with dioxygen in air without recourse to metal catalysts. It represents an important step toward the development of a general, economical, and benign catalytic redox dehydration protocol.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article，once mentioned of 33100-27-5, Quality Control of: 1,4,7,10,13-Pentaoxacyclopentadecane

Thermodynamic functions of complex formation of 15-crown-5 ether (15C5) with sodium cation (Na+) in the mixtures of propan-1-ol (PrOH) with water (W) at different temperatures have been calculated. To obtain this function two experimental methods have been used. The equilibrium constants of complex formation (15C5/Na+) have been determined by conductivity measurements and the enthalpic effect of complex formation has been measured by the calorimetric method and has been also calculated using van’t Hoff’s equation. The complexes are enthalpy stabilized but entropy destabilized. Effect of solvent properties on the process of complex 15C5/Na+ formation in PrOH + W mixtures has been discussed. The obtained results were compared with analogous data in the mixtures of water with methanol or ethanol and discussed.
