1. Cuprous iodide has a wide range of applications, including as an organic synthesis catalyst, resin modifier, artificial rainmaking agent, anode tube covering, and iodine source in iodized salts. In the presence of 1,2- or 1,3-diamine ligands, cuprous iodide can catalyze the conversion of brominated aromatics, brominated heterocyclic compounds, and vinyl bromides to their corresponding iodides. The reaction is generally carried out in dioxane solvent, using sodium iodide as the iodizing agent. Aromatic iodides are generally more reactive than their corresponding chlorides and iodides; therefore, cuprous iodide can catalyze a series of coupling reactions involving haloalkanes, such as the Heck reaction, Stille reaction, Suzuki reaction, and Ullmann reaction. 2-Bromo-1-octen-3-ol and 1-nonyne undergo a coupling reaction in the presence of dichlorobis(triphenylphosphine)palladium(II), cuprous chloride, and diethylamine to produce 7-methylene-8-hexadec-6-ol.
2. It is used as an organic reaction catalyst, anode tube covering, and also as an animal feed additive.
3. It acts as a catalyst in many reactions involving Grignard reagents, and cuprous iodide is also used in the dry Wiff rearrangement reaction. | [Cuprous halide]
Cuprous Iodide and cuprous chloride, cuprous bromide are three common cuprous halides, three are white solid, the photonasty of cuprous iodide is worse than CuBr and CuCl, in light decomposition and precipitation of iodine. In nature, it exists in marshite. Cuprous chloride and cuprous bromide can be produced by the reaction of the corresponding acidic solution of divalent copper salt with copper. Cuprous Iodide was prepared by adding Cu2 + into potassium iodide solution.
Cuprous iodide and Magnesium bromide or lithium phenyl in ether can produce copper phenyl.
The reaction of methyl lithium with cuprous iodide at-15 ℃ or by the reaction of copper nitrate and tetramethyl lead in ethanol at-60 ~-40 ℃ can produce methyl copper.
Grignard reagent reacts with cuprous halide to produce cuprous hydrocarbyl, cuprous halide may be cuprous iodide, cuprous bromide, cuprous chloride.
