Draw the Lewis structure of calcium chloride. For the given reaction, label the Lewis acid and base. Use curved arrow notation to show the movement of electron pairs. Draw the structure of the product in the following reaction of aniline with CH3Cl in the presence of AlCl3...
The diastereoselectivity of the addition was found to be remarkably sensitive to the structure of the phosphoramide promoter. The results of the uncatalyzed reaction are reiterated to recall a 49/1 selectivity favoring the syn diastereomer. When the reactions are promoted by a catalytic amount of ...
Tungsten nitride films were deposited on heated substrates by the reaction of vapors of tungsten bis(alkylimide)bis(dialkylamide) and a Lewis base or a hydrogen plasma. For example, vapors of tungsten bis(tert-butylimide)bis(dimethylamide) and ammonia gas supplied in alternate doses to surfaces...
Interestingly, the structure of the SeO2∙∙∙CH3OCH3 complex possesses C1 symmetry, whilst its S analog has Cs symmetry. The remaining complexes exhibit C1 symmetry. Figure 2. The optimized geometries of the global minima of the studied chalcogen-bonded complexes. The purple and green ...
The results showed that aromatics yield can be improved by the reduced transport resistance of the mesoporous structure, and by non-framework Lewis acidic Al species as well. 2. Results and Discussion Table 1 lists the porosities of the tested catalysts. The total surface area, the micropore ...
