2I − ⇌ I 2 + E° = 0.54 volts (versus SHE) Because iodide is easily oxidized, some enzymes readily convert it into electrophilic iodinating agents, as required for the biosynthesis of myriad iodide-containing natural products .
Mercury(I) iodide is a chemical compound of mercury and iodine. The chemical formula is Hg 2 I 2. ... The compound is often formulated as Hg 2 2+ 2I ...
Hydrogen iodide. The simplest compound of iodine is hydrogen iodide, HI.It is a colourless gas that reacts with oxygen to give water and iodine. Although it is useful in iodination reactions in the laboratory, it does not have large-scale industrial uses, unlike the other hydrogen halides.
Cyclopentadienyliron dicarbonyl iodide is an organoiron compound with the formula (C 5 H 5)Fe(CO) 2 I. It is a dark brown solid that is soluble in common organic solvents. (C 5 H 5)Fe(CO) 2 I, or FpI as it is often known, is an intermediate for the preparation of other organoiron compounds such as in ferraboranes.
Mercury(II) iodide is a semiconductor material, used in some x-ray and gamma ray detection and imaging devices operating at room temperatures. [5] In veterinary medicine, mercury(II) iodide is used in blister ointments in exostoses, bursal enlargement, etc. [citation needed] It can appear as a precipitate in many reactions.
In this protocol, iodide ion is generated by the following slow reaction between the iodate and bisulfite: IO − 3 + 3 HSO − 3 → I − + 3 HSO − 4. This first step is the rate determining step. Next, the iodate in excess will oxidize the iodide generated above to form iodine: IO − 3 + 5 I − + 6 H + → 3 I 2 + 3 H 2 O
Iodine dioxide is a binary inorganic compound of iodine and oxygen with the chemical formula IO 2. [1] [2] Only stable as a dilute gas, [3] this compound is one of many iodine oxides, [4] [5] and "iodine dioxide" is sometimes used to describe its formal dimer, the salt diiodine tetroxide (I 2 O 4, [IO] + [IO 3] −).
Samarium(II) iodide is a reagent for carbon-carbon bond formation, for example in a Barbier reaction (similar to the Grignard reaction) between a ketone and an alkyl iodide to form a tertiary alcohol: [9] R 1 I + R 2 COR 3 → R 1 R 2 C(OH)R 3 Barbier reaction using SmI 2. Typical reaction conditions use SmI 2 in THF in the presence of ...
