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
Mercury (toy manufacturer) Mercury (toy manufacturer) Mercury is a brand of diecast toy cars manufactured in Italy from about 1945 through the 1970s. Along with Dinky Toys in England, Mercury was a pioneer in 1:43 scale diecast toys made in Europe. Today, Mercury models are rather rare and not easy to find. The company logo was the word Mercury within a rectangle with a round toothed gear behind the company name. As with many toy car makers, Turin-based Mercury started as a diecaster of small parts. It produced metal parts mainly for auto companies (History of Mercury 2013). Later an importer for German
