Iodosilane

Template:Chembox 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.

$\mathrm{C}\mathrm{l}{\mathrm{C}}_{\mathrm{6}}{\mathrm{H}}_{\mathrm{4}}\mathrm{S}\mathrm{i}{\mathrm{H}}_{\mathrm{3}}\mathrm{+}\mathrm{H}\mathrm{I}\mathrm{⟶}{\mathrm{C}}_{\mathrm{6}}{\mathrm{H}}_{\mathrm{5}}\mathrm{C}\mathrm{l}\mathrm{+}\mathrm{S}\mathrm{i}{\mathrm{H}}_{\mathrm{3}}\mathrm{I}$

Properties

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