Asymmetric photoreactions within zeolites: role of confinement and Alkali Metal Ions

Article Abstract:

Four strategies for asymmetric induction in organic photochemistry that derive their success from the use of a confined reaction cavity is explored. Examination of the zeolite interior suggests that the most likely factor responsible for the change in diastereomeric excess(de) or enantiomeric excess(ee) is the difference in conformational preference for the reactant molecules.

Analogies between Boron and Carbon

Article Abstract:

Even though carbon and boron are neighbors in the periodic table they differ quite a lot. Many similarities between the two that were not noticed earlier are presented.
