'''四苯基硅'''是一种{{link-de|碳硅烷|Carbosilane}}，化学式 {{chem2|(C6H5)4Si}}。

== 制备 ==
四苯基硅是在1886年由 A. Polis 通过[[四氯化硅]]、[[氯苯]]和金属[[钠]]在[[乙醚]]的反应，首次制备的。<ref name="Chem_Ber_1886_1012" />
:<math>\mathrm{4 \ ClC_6H_5 + \ SiCl_4 \ + \ 8 \ Na \longrightarrow Si(C_6H_5)_4 + 8 \ NaCl}</math>

它也可以由[[苯基锂]]和[[四氯化硅]]反应而成。<ref name="J. Derek Woollins">{{cite book|author=J.

:<math>\mathrm{4 \ LiC_6H_5 + SiCl_4 \longrightarrow Si(C_6H_5)_4 + 4 \ LiCl}</math>
四苯基硅也可以由[[八苯基环丁硅烷]]分解而成。<ref name="Elsevier Science & Technology Books">{{cite book|author=Elsevier Science & Technology Books |title=ADVANCES ORGANOMETALLIC CHEMISTRY |publisher=Academic Press |date=1964 |ISBN= |page=117 }}</ref>

== 性质==
四苯基硅是一种白色固体，不溶于水。<ref name="Alfa" />它很稳定，加热到 550&nbsp;°C 也不会分解。<ref name="Rochow2013" />它难溶于乙醚和[[乙醇]]，易溶于热的[[苯]]。<ref name="Chem_Ber_1886_1012" />
