Webto hard Lewis bases. Iron(0) mostly coordinates five or six ligands with trigonal bipyramidal and octahedral geometry. Iron(–II) is tetrahedrally coordinated. Iron in low oxidation states is most interesting for organometallic chemistry and in particular for iron-catalyzed reactions because they can form more reactive WebRemoval of one halogen atom from an organohalides generates highly reactive radicals. This fact has multiple consequences: monodehalogenation is usually accompanied by coupling of the resulting radical: when a pair of halides are mutually adjacent (vicinal), their removal favored. Vicinal alkyl dihalides convert to alkenes. Magnesium can be used:
