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.
C l C 6 H 4 S i H 3 + H I ⟶ C 6 H 5 C l + S i H 3 I {\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.
