Because nucleophiles donate electrons, they fit the definition of Lewis bases.

It can react with Lewis bases, a group of chemicals.

It forms adducts with a variety of Lewis bases.

Simplest are those that react directly with the Lewis base.

Other common Lewis bases include pyridine and its derivatives.

It has a high donor number, making it a strong Lewis base.

Metathesis reactions may be carried out with strong Lewis bases.

There is reason to believe that this central atom is an amine which functions as a Lewis base.

A Lewis base is a substance that gives two electrons in the bonding.

When the Lewis bases is an amines, adducts are also formed.
