Metal carbonyl 18-electron complexes is sometimes catalysed by catalytic amounts of oxidants, via electron-transfer. Metal carbonyls react with reducing agents such as metallic sodium or sodium amalgam to give carbonylmetalate (or carbonylate) anions: For iron pentacarbonyl, one obtains the tetracarbonylferrate with loss of CO: Mercury can insert into the metal-metal bonds of some polynuclear metal carbonyls: The CO ligand is often susceptible to attack by nucleophiles. For example, trimethylamine oxide and bistrimethylsilylamide convert CO ligands to CO and CN, respectively. In the "Hieber base reaction", hydroxide ion attacks the CO ligand to give a metallacarboxylic acid, followed by the release of carbon
Trifluoroacetyl chloride magnesium, mercury, silver, or cadmium. When trifluoroacetyl chloride also reacts with ketene and esterification yields occur, the resulting reaction forms trifluoroacetoacetate esters. Trifluoroacetyl chloride also reacts with soil, cellulose-based absorbents, and clay-based absorbents. When the compound reacts with water in contact with metal, hydrogen gas, which is explosive, is produced. The compound forms a clustering reaction with a methyl group (CH). Trifluoroacetyl chloride can be produced by catalytic chlorination of chlorine and trifluoroacetaldehyde. The compound can also be produced if halothane is oxidized using CYP2E1. This is also done with CYP2A6 instead of CPY2E1, but less readily. Trifluoroacetyl chloride's applications
