Examples of Lewis Bases: OH-, F-, H2O, ROH, NH3, SO42-, H-, CO, PR3, C6H6. Lewis Acid Example An example of an acid/base reaction that can't be described by the Bronsted-Lowry definition is Al3+ in water. Aluminum Hexa-aqua Complex Al3+ is a hard Lewis acid. It react...
Lewis Acid/Base Theory A Lewis base is a species with an available (reactive) pair of electrons and a Lewis acid is an electron pair acceptor. The simplest reaction is for a Lewis acid to interact with a Lewis base to give a Lewis acid/base complex:...
Theoretical studies for Lewis acid-base interactions and C-H...O weak hydrogen bonding in various CO2 complexes. Comprehension of the basic concepts for the design of CO2-philic molecules is important due to the possibility for "green" chemistry in supercritical CO2 of substitute solvent systems....
The reaction described above indicated that β,γ-unsaturated 2-acyl imidazoles performed both α-addition reaction and β-addition upon isomerization under proper Lewis acid catalysts. Next, to extend the scope of α-addition of β,γ-unsaturated 2-acyl imidazoles, several types of imines3were ex...
