**三碘甲矽烷**是一種鹵代甲矽烷，化學式 SiHI 
3。

## 製備

三碘甲矽烷可以由三氯甲矽烷和苯胺的苯溶液和碘化氫的兩步反應而成。

　
: $\mathrm {SiHCl_{3}+6\ C_{6}H_{5}NH_{2}\longrightarrow SiH(NHC_{6}H_{5})_{3}+3\ [C_{6}H_{5}NH_{3}]Cl} $

　
: $\mathrm {SiH(NHC_{6}H_{5})_{3}+6\ HI\longrightarrow SiHI_{3}+3\ [C_{6}H_{5}NH_{3}]I} $

三碘甲矽烷也可以由矽和碘化氫反應而成，類似三溴甲矽烷，不過量很少。 這個反應在 1857 年三溴甲矽烷首次合成時，就被弗里德里希・維勒和 Heinrich Buff 描述了。

　
: $\mathrm {Si+3\ HI\rightarrow SiHI_{3}+H_{2}} $

它也可以由三氯甲矽烷和氨里的碘化銨反應而成。

它也可以由三苯甲矽烷和碘化氫反應而成。這個反應由氯化鋁催化。

　
: $\mathrm {SiH(C_{6}H_{5})_{3}+3\ HI\longrightarrow SiHI_{3}+3\ C_{6}H_{6}} $

## 性質

三碘甲矽烷是一種無色，易水解，易光解的液體。

## 用處

三碘甲矽烷和二碘甲矽烷可以用來分離矽層。
