a) Doubly bridging and b) terminal oxo ligands. A transition metal oxo complex is a coordination complex containing an oxo ligand. Formally O 2–, an oxo ligand can be bound to one or more metal centers, i.e. it can exist as a terminal or (most commonly) as bridging ligands. Oxo ligands stabilize high oxidation states of a metal.

Hydroformylation of an alkene (R 1 to R 3 organyl groups (i. e. alkyl-or aryl group) or hydrogen). In organic chemistry, hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes (R−CH=O) from alkenes (R 2 C=CR 2).
Oxo ligand, a divalent ligand; oxo-, a prefix in the formal IUPAC nomenclature for the functional group '=O' (a substituent oxygen atom connected to another atom by a double bond) Hydroformylation, an industrial process for the production of aldehydes from alkenes
The positions of other groups are indicated by Greek letters, the α-carbon being the atom adjacent to carbonyl group. Although used infrequently, oxo is the IUPAC nomenclature for the oxo group (=O) and used as prefix when the ketone does not have the highest priority. Other prefixes, however, are also used.
In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.
In organic chemistry, keto acids or ketoacids (also called oxo acids or oxoacids) are organic compounds that contain a carboxylic acid group (−COOH) and a ketone group (>C=O). [1] In several cases, the keto group is hydrated. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in ...
If other functional groups are present, the chain is numbered such that the aldehyde carbon is in the "1" position, unless functional groups of higher precedence are present. If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH 2 COOH is 3-oxopropanoic acid.
Oxophilic main group compounds are also well known and useful. The highly oxophilic reagent Si 2 Cl 6 stereospecifically deoxygenates phosphine oxides. [5] Phosphorus pentasulfide and the related Lawesson's reagent convert certain organic carbonyls to the corresponding sulfur derivatives: P 4 S 10 + n R 2 C=O → P 4 S 10−n O n + n R 2 C=S
