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.^[4]

${\displaystyle \mathrm {ClC_{6}H_{4}SiH_{3}+HI\longrightarrow C_{6}H_{5}Cl+SiH_{3}I} }$

Properties

At low temperatures, iodosilane quickly reacts with [Co(CO)₄]⁻ to form SiH₃Co(CO)₄.^[5]
