Iodosilane Explained

Iodosilane is a chemical compound of silicon, hydrogen, and iodine. It is a colorless monoclinic crystal of space group P2₁/c at −157 °C.

Preparation

Iodosilane is the first product of the reaction between monosilane and iodine, the other products being di-, tri- and finally tetraiodosilane (silicon tetraiodide).

It can also be produced by the reaction of phenylsilane or chlorophenylsilane with hydrogen iodide.^[1]

ClC _{6H} _{4SiH} _{3} +HI\longrightarrowC _{6} H _{5} Cl+SiH _{3I}

Properties

At low temperatures, iodosilant quickly reacts with [Co(CO)₄]⁻ to form SiH₃Co(CO)₄.^[2]
