Boron triiodide Usage And Synthesis

Chemical Properties

needles or crystal(s) with 99.9% purity; unstable; enthalpy of vaporization 40.5 kJ/mol. It is a crystalline solid, which reacts vigorously with water to form hydroiodic acid and boric acid. Boron triiodide is easily decomposed when heated, and reacts with red phosphorus or white phosphorus to incandescent.
Boron triiodide is an electron-deficient compound with unsaturated boron atoms, so its chemical properties are mainly Lewis acid properties, and it can react with various Lewis bases to form complexes.

Uses

Boron triiodide is used as pharmaceutical, chemical and organic intermediate. It is also used as a catalyst and for preparation of boron compounds.

Uses

Boron triiodide can be used as a reagent to cleave C-O bonds in ethers, esters, and alcohols. It can also be used to cleave silanes and halides. Boron triiodide converts alcohols to alkyl iodides; sulfonyl and sulfinyl to disulfides. Borylation of triarylamines can be achievd using this reagent.
It can also be used to prepare imidazole based imino aluminum dihalide metal complexes and boron carbonitride (BCN) nanowires.

Preparation

Boron triiodide can be synthesized by refluxing lithium borohydride and iodine in hexane, or by reacting alkali metal borohydride with iodine at a suitable temperature.

General Description

Boron triiodide is a strong Lewis acid. It can be prepared by treating iodine (I₂) with potassium borohydride (KBH₄) in heptane.
