Fundamentals of Asymmetric Catalysis
The achiral copper Lewis acid and the chiral Lewis base combine to give rise to
the catalytic species. Nonetheless, this reaction is classified here as an example
of Lewis base catalysis because much less chiral Lewis base is used than ...

Here SO3 accepts the electron pair from the O2 ion. At the same time, an electron
pair from the SPO bond moves to the O atom. Thus, O2 is the Lewis base and
SO3 is the Lewis acid. The Lewis concept embraces many reactions that we
might ...

Lewis Basicity and Affinity Scales: Data and Measurement
The Lewis concept of acids and bases is discussed in every general, organic and inorganic chemistry textbook. This is usually just a descriptive treatment, as it is not possible to devise a single numerical scale suitable for all occasions.
