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 pollution in the ocean this goal. Proper disposal of mercury containing items such as medicinal packaging and thermometers, using mercury-free bulbs and batteries, buying consumer products with zero or minimum mercury emission to the environment can make a significant difference in recovering world’s ecosystems from mercury pollution leaving minimum legacy of mercury pollution in the ocean for our future generations. Mercury pollution in the ocean Mercury is a toxic heavy metal which cycles through atmosphere, water, and soil in various forms to different parts of the world. Due to this natural cycle, irrespective of which part of the world releases mercury it could affect
