There are three sets of Indium halides, the trihalides, the monohalides, and several intermediate halides. In the monohalides the oxidation state of indium is +1 and their proper names are indium(I) fluoride, indium(I) chloride, indium(I) bromide and indium(I) iodide. The intermediate halides contain indium with oxidation states, +1, +2 and +3.
The Barbier reaction is an organometallic reaction between an alkyl halide (chloride, bromide, iodide), a carbonyl group and a metal. The reaction can be performed using magnesium, aluminium, zinc, indium, tin, samarium, barium or their salts. The reaction product is a primary, secondary or tertiary alcohol.
Partial oxidation of a halide: 2 PCl 3 + O 2 → 2 POCl 3. In this example, the oxidation state increases by two and the electrical charge is unchanged. Partial halogenation of an oxide: 2 V 2 O 5 + 6 Cl 2 + 3 C → 4 VOCl 3 + 3 CO 2; Oxide replacement: CrO 2− 4 + 2 Cl − + 4 H + → CrO 2 Cl 2 + 4 H 2 O
IMAs proceed in two steps: first, indium reacts with the allyl halide, give an allyl-In(III) intermediate, second, this allyl indide reacts with an electrophile: The reaction is conducted under the conditions of a Barbier reaction where the indium, allyl halide, and electrophile are all mixed in a one-pot process.
The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}} See also [ edit ]
Less frequently, indium forms compounds in oxidation state +2 and even fractional oxidation states. Usually such materials feature In–In bonding, most notably in the halides In 2 X 4 and [In 2 X 6 ] 2− , [ 43 ] and various subchalcogenides such as In 4 Se 3 . [ 44 ]
InCl can be prepared by heating indium metal with indium trichloride in a sealed tube. [3] [4] According to X-ray crystallography, the structure of the yellow polymorph resembles that of sodium chloride except that the Cl-In-Cl angles are not 90°, but range between 71 and 130°. The red (high T) polymorph crystallizes in the thallium(I) iodide ...
Radii in picometers of common halogen atoms (gray/black) and the corresponding halide anions (blue) In chemistry, a halide (rarely halogenide [1]) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or ...
