General description

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

Application

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.

The reaction of bis(2,6-diisopropylphenyl)imidazolin-2-imine (LH, 1) with Me3N·AlH3 furnishes {μ-LAlH2}2 (2). The marked tendency of 2 to release its hydride substituents is ascribed to the strong electron-donor character of the imidazolin-2-iminato ligand. This is supported by its reactivity study and
