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
Gold Is the Metal (With the Broadest Shoulders) Side A: Side B: Gold Is the Metal (With the Broadest Shoulders) Gold Is the Metal (With the Broadest Shoulders) was the third album released by Coil in the year 1987. It is not a proper follow-up to 1986's "Horse Rotorvator", but more a collection of outtakes and demos from the "Scatology", "Horse Rotorvator" and "Hellraiser" soundtrack sessions. Some obviously correspond to earlier and later released material ("Golden Hole" to "Penetralia", "...Of Free Enterprise" to "Herald", etc.), while others ("Boy In a Suitcase") do not appear anywhere else. "The Last Rites Of Spring" includes a sample by Stravinsky, also used
