- EDTA, ethylenediaminetetraacetic acid, has four carboxyl groups and two amine groups that can act as electron pair donors, or Lewis bases.
- BF 3 is commonly referred to as " electron deficient, " a description that is reinforced by its exothermic reactivity toward Lewis bases.
- A difference between HB and XB is since halogen atoms are Lewis bases, a halogen atom can both donate and accept in a halogen bond.
- Utilization of chiral Lewis acid complexes and Lewis bases in asymmetric catalytic processes is the fastest-growing area in the usage of the Mukaiyama aldol reaction.
- Transition metal complexes should initially satisfy the eighteen electron rule, have no net charge, and their ligands should be two electron donors ( Lewis bases ).
- It has been proposed that amines act as Lewis bases and bind to Lewis acidic Cu surface sites in YBa 2 Cu 3 O 7 to form stable coordination bonds.
- Lewis acids tend to be electron-withdrawing / electrophilic; Lewis bases, electron donating / nucleophilic . talk ) 16 : 04, 6 July 2010 ( UTC)
- Interestingly, although alcohols and amines can be Br�nsted-Lowry acids, they can also function as Lewis bases due to the lone pairs of electrons on their oxygen and nitrogen atoms.
