Definitions

1. Carbonyls are coordination complexes between transition metals and carbonyl ligands. (Web site)
2. Carbonyls are also the prototypical groups with vinylogous reactivity, e.g. (Web site)
3. Carbonyls are produced in large amounts under lean operating conditions, especially when oxygenated fuels are used. (Web site)
4. Most carbonyls are toxic, and the carboxylic acids can corrode metals. (Web site)
5. Metal carbonyls are coordination complexes of transition metals with carbon monoxide.[1] These complexes may be homoleptic, i.e. (Web site)

Emission

1. The emission of carbonyls can be controlled by combustion stoichiometry and exhaust catalysts. (Web site)

Reagent

1. SO 2 Cl 2 is widely used as a reagent in the conversion of C-H → C-Cl adjacent to activating substituents such as carbonyls and sulfoxides. (Web site)

Alkyl Groups

1. Except under special conditions, reducing agents do not reduce carbonyls all the way to alkyl groups, they stop at the alcohol. (Web site)

Attack

1. Like other low-valent metal carbonyls, Ni(CO) 4 is susceptible to attack by nucleophiles. (Web site)

Nucleophilic

1. These compounds, being nucleophilic at the α-carbon, can attack especially reactive protonated carbonyls such as protonated aldehydes. (Web site)

Molecular Formula

1. From the molecular formula, the compound has "five degrees of unsaturation " (six double bonds, carbonyls or rings). (Web site)

Alkali Metals

1. Ketyls can be formed as radical anions by one-electron reduction of carbonyls with alkali metals. (Web site)

Nucleophile

1. The Gilman reagent is an effective nucleophile for 1,4-additions to conjugated carbonyls.

Aldol

1. Unsaturated carbonyls can be prepared in the laboratory in an aldol reaction and in the Perkin reaction. (Web site)

Imines

1. With nucleophiles, pyridine reacts via its 2nd and 4th carbon atoms and thus behaves similar to imines and carbonyls.

Higher Concentration

1. Accordingly, the treatment disclosed in EP 487,284 did not take advantage of the higher concentration of carbonyls in the vent gas condensate stream. (Web site)

Oxygens

1. Turns out, if you wire the phenyl group directyly to the tropane ring (no oxygens or carbonyls, or whatever), potency increases. (Web site)

Amines

1. Condensation of amines with carbonyls in alkylimino-de-oxo-bisubstitution.

Metal

1. In contrast to PF 3, alkyl- and arylphosphines can be substituted for CO in metal carbonyls, but rarely give homoleptic complexes analogous to the carbonyls.
2. The high pressure reactions catalysed by heavy metal acetylides, especially copper acetylide, or metal carbonyls are called Reppe Chemistry. (Web site)

Metals

1. Although nickel carbonyl and iron pentacarbonyl form upon treatment of the metals with carbon monoxide, most metal carbonyls are prepared less directly. (Web site)

Enolate

1. The deprotonation of the enol with a strong base produces an enolate, which is a powerful nucleophile and can alkylate electrophiles such as other carbonyls. (Web site)
2. The Michael reaction involves conjugate additions of enolate s to Conjugated carbonyls.

Enolates

1. Carbonyls also be alkylated by enolates as in aldol reactions. (Web site)
2. The Michael reaction involves conjugate additions of enolates to Conjugated carbonyls. (Web site)

Carbonyls

1. Carbon monoxide is also used in reactions with metals such as nickel, iron, and cobalt to form some types of carbonyls. (Web site)
2. In nickel carbonyl and other carbonyls, the electron pair on the carbon interacts with the metal; the carbon monoxide donates the electron pair to the metal. (Web site)
3. Carbonyls can be alkylated by nucleophilic attack by organometallic reagents such as organolithium reagents and Grignard reagents. (Web site)
