Beyond the classical Lewis bases and anions, all unsaturated molecules are also ligands, utilizing their pi electrons in forming the coordinate bond.
22.
EDTA, ethylenediaminetetraacetic acid, has four carboxyl groups and two amine groups that can act as electron pair donors, or Lewis bases.
23.
BF 3 is commonly referred to as " electron deficient, " a description that is reinforced by its exothermic reactivity toward Lewis bases.
24.
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.
25.
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.
26.
Transition metal complexes should initially satisfy the eighteen electron rule, have no net charge, and their ligands should be two electron donors ( Lewis bases ).
27.
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.
28.
Lewis acids tend to be electron-withdrawing / electrophilic; Lewis bases, electron donating / nucleophilic . talk ) 16 : 04, 6 July 2010 ( UTC)
29.
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.
30.
Oxohalide anions such as [ VOCl 4 ] 2 " can be seen as acid-base complexes of the oxohalide ( VOCl 2 ) with more halide ions acting as Lewis bases.
