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
Viet Mercury other hand, Harris sent a letter to competing newspapers implying that they had stolen his issues from news racks. Within months of "Viet Mercury"s publication, "Vietnam Family" () and another Vietnamese paper failed. "Viet Mercury" became profitable in 2000. With circulation rising to 35,000, "Viet Mercury" began publishing daily in March 2003. Unlike its competitors, "Viet Mercury" operated like a mainstream news outlet, with a full-time staff that produced original reporting and had access to the "Mercury News" Hanoi bureau. An investigative series by "Viet Mercury" uncovered doctors embezzling money from recent immigrants, leading to the arrests of several doctors.
