'''三碘甲硅烷'''是一种卤代[[甲硅烷]]，化学式 {{chem|SiHI|3}}。

== 制备 ==
三碘甲硅烷可以由[[三氯甲硅烷]]和[[苯胺]]的[[苯]]溶液和[[碘化氢]]的两步反应而成。<ref name="brauer" />

:<math>\mathrm{SiHCl_3 + 6 \ C_6H_5NH_2 \longrightarrow SiH(NHC_6H_5)_3 + 3 \ [C_6H_5NH_3]Cl}</math>

:<math>\mathrm{SiH(NHC_6H_5)_3 + 6 \ HI \longrightarrow SiHI_3 + 3 \ [C_6H_5NH_3]I}</math>

三碘甲硅烷也可以由[[硅]]和碘化氢反应而成，类似[[三溴甲硅烷]]，不过量很少。<ref name="brauer" />  这个反应在1857年三溴甲硅烷首次合成时，就被[[弗里德里希·维勒]]和{{link-de|Heinrich Buff}}描述了。<ref name="J_L_Ann_Chem1857_104_94">{{Literatur| Autor=H. Buff, F. Wöhler|Titel=Ueber neue Verbindungen des Siliciums|Sammelwerk=Annalen der Chemie und Pharmacie| Band=104| Nummer=1|Jahr=1857|Seiten=94-109|DOI=10.1002/jlac.18571040108}}</ref> 
:<math>\mathrm{Si + 3 \ HI \rightarrow SiHI_3 + H_2 }</math>

它也可以由三氯甲硅烷和[[氨]]里的[[碘化铵]]反应而成。<ref name="E. G. Rochow">{{cite book| author=E. G. Rochow | title=The Chemistry of Silicon Pergamon International Library of Science, Technology, Engineering and Social Studies | publisher=Elsevier | ISBN=978-1-4831-8755-6 | date=2013 | page=1371 }}</ref>

它也可以由[[三苯甲硅烷]]和碘化氢反应而成。这个反应由[[氯化铝]][[催化]]。<ref name="DOI10.1021/cm00010a029" />
:<math>\mathrm{SiH(C_6H_5)_3 + 3 \ HI \longrightarrow SiHI_3 + 3 \ C_6H_6}</math>

== 性质==
三碘甲硅烷是一种无色，易[[水解]]，易光解的液体。<ref name="brauer" /><ref name="R. Blachnik">{{cite book| author=R. Blachnik | title=Taschenbuch für Chemiker und Physiker Band 3: Elemente, anorganische Verbindungen und Materialien, Minerale | publisher=Springer-Verlag | ISBN=978-3-642-58842-6 | date=2013 | page=730 }}</ref>

== 用处==
三碘甲硅烷和[[二碘甲硅烷]]可以用来分离硅层。<ref name="DOI10.1021/cm00010a029">G. Tamizhmani, Michael Cocivera, Richard T.
