Typical Ligands That Often Behave As Redox Non-Innocent Ligands
- O2 and NO.
Ligands with extended pi-delocalization such as porphyrins and phthalocyanines, ligands with the generalised formulas 2- or D=CR-CR=D (D = O, S, NR’ and R, R' = alkyl or aryl), and similar related systems are often non-innocent. For example:
- dioxalenes, such as catecholates.
- dithiolenes, such as 1,2-maleonitriledithiolate
- diimines such as derivatives of 1,2-diaminobenzene, α-diimines, and dimethylglyoxime.
- pyridine-2,6-diimine ligands (relevant in polymerisation and hydrogenation catalysis).
The pyridine-2,6-diimine ligand can be easily reduced by one or two electrons.

Famous quotes containing the words typical and/or behave:
“A building is akin to dogma; it is insolent, like dogma. Whether or no it is permanent, it claims permanence, like a dogma. People ask why we have no typical architecture of the modern world, like impressionism in painting. Surely it is obviously because we have not enough dogmas; we cannot bear to see anything in the sky that is solid and enduring, anything in the sky that does not change like the clouds of the sky.”
—Gilbert Keith Chesterton (1874–1936)
“The relationship between mother and professional has not been a partnership in which both work together on behalf of the child, in which the expert helps the mother achieve her own goals for her child. Instead, professionals often behave as if they alone are advocates for the child; as if they are the guardians of the child’s needs; as if the mother left to her own devices will surely damage the child and only the professional can rescue him.”
—Elaine Heffner (20th century)
