The toxicity of a given metal carbonyl depends on the toxicity of carbon monoxide and of the metal from which it is derived, as well as the volatility and instability of the carbonyl itself.
In coordination complexes the carbon monoxide ligand is called carbonyl.
The production of sintered nickel from nickel carbonyl, although done in sealed machinery, involves potential exposure to extremely toxic nickel carbonyl and carbon monoxide.

The production of sintered nickel from nickel carbonyl, although done in sealed machinery, involves potential exposure to extremely toxic nickel carbonyl and carbon monoxide.
The solid precursor (52, 152) can, for example, be a ruthenium carbonyl or a rhenium carbonyl.
Novel carbonyl hydrolase variants derived from the DNA sequences of naturally-occuring or recombinant non-human carbonyl hydrolases are disclosed.
A metal carbonyl precursor parameter may be monitored to determine a status of the metal carbonyl precursor (3a) and the need for purifying the metal carbonyl precursor (3a).
The aim was to find a process making it possible for economically desorbing nickel and iron carbonyls bound to the activated carbon in the removal of carbonyl from gases containing a great deal of hydrogen sulphide.
These carbonyl stress-ameliorating agents rapidly eliminate carbonyl compounds and thus ameliorate carbonyl stress conditions.
The carbonyl compound can be recovered and reused.
Nickel carbonyl is carcinogenic and teratogenic in rats; the European Union has classified nickel carbonyl as an animal teratogen.
Protonation of the carbonyl oxygen (Step 1, arrows A and B) makes the carbonyl carbon a much better electrophile.
Phosgene: Carbonyl dichloride (CAS 75-44-5)
Disclosed is a simple and highly efficient process for producing an aromatic carbonyl compound, which can produce an aromatic carbonyl compound having a substituent introduced to an aromatic ring adjacent to a carbonyl group.
Nickel carbonyl is carcinogenic and teratogenic in rats; the European Union has classified nickel carbonyl as an animal teratogen.
It is easy for a weak nucleophile to attack the carbon.
Whenever the carbonyl group is an aldehyde, the monosaccharide is the aldose; if the carbonyl group is a ketone, the monosaccharide is a ketose.
If the carbonyl group is an aldehyde , the monosaccharide is an aldose ; if the carbonyl group is a ketone , the monosaccharide is a ketose.
Mechanism: Protonation of the oxygen of the ketone (Step 1, arrows A and B) makes the carbonyl carbon a better electrophile.
Protonation of nitrogen by acid (Step 1, arrows A and B) makes the attached carbon more electrophilic.
The furan derivative compound is then subjected to a self-aldol condensation reaction or a crossed- aldol condensation reaction with another carbonyl compound to yield a beta-hydroxy carbonyl compound and/or an alpha-beta unsaturated carbonyl compound.
The carbonyl group is not at the end of the chain.

If the carbonyl group is an aldehyde, the monosaccharide is an aldose if the carbonyl group is a ketone, the monosaccharide is a ketose.
