{eq}BCl_3, \ NO_2, \ BH_3 {/eq} Lewis Dot Structure: Lewis dot structures are the diagrammatic representation of bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecules. Lewis dot structures are also known as Lewis dot diagr...
Lewis Dots and DiagramsThe diagram representing how the valance electrons around atoms in a molecule are arranged is often referred to as a Lewis dot diagram or Lewis structure. Electrons can be drawn using bond lines where each line represents two electrons (e.g., a triple bond represents 6...

3)发展了一种新颖的Lewis酸/Brønsted酸共催化体系,通过协同催化,原位脱除三级醇硅醚保护基的方式,实现易脱水的三级醇对1,4-二烯酮的分子内跨环氧杂Michael加成反应构建Sinulochmodin C骨架中高张力的氧桥环。 该工作提供了一种新颖的关环策略,高效构建了该类天然产物的核心骨架,为将来的药物化学研究打下了物质...
structure further, the method developed by Feng et al. was applied to quantify the accessible Lewis acidic sites in MOFs, and the results are shown inTable 1[40]. For the sample synthesised without modulator, the amount of Lewis acidic sites is too low to be detected. A significant ...
Table 3. Textural properties of studied samples. 2.3. Surface Acidity Temperature-Programmed Desorption of Ammonia (TPD-NH3) is one of the most common methods for characterizing the total Lewis acidity in zeolites. The amount of ammonia desorbed over a given temperature range is taken as a mea...
