'''二苯基硅烷'''是化学式 (C<sub>6</sub>H<sub>5</sub>)<sub>2</sub>SiH<sub>2</sub>的[[有机硅化合物]]。

== 制备 ==
二苯基硅烷可以由[[二苯基二氯硅烷]]和[[氢化铝锂]]或[[氢化锂]]反应而成：<ref name="Astruc2007"/><ref name="Gelest"/>
: <math>\mathrm{2 \ Cl_2Si(C_6H_5)_2 + \ LiAlH_4 \xrightarrow{} \ 2 \ H_2Si(C_6H_5)_2 \ + \ LiCl \ + \ AlCl_3 }</math>

== 反应==
相较于对应的碳化合物[[二苯基甲烷]]，二苯基硅烷更容易被金属氧化物（例如[[氧化汞]]）氧化，形成[[二苯基硅二醇]]：<ref name="Gelest"/>
: <math>\mathrm{H_2Si(C_6H_5)_2 + 2 \ HgO \xrightarrow[MePh]{-80\, {}^{\circ}C}\ (HO)_2Si(C_6H_5)_2 \ + 2 \ Hg }</math>
二苯基硅烷对[[水解]]稳定，但在酸或碱[[催化]]下，它会水解成二苯基硅二醇：<ref name="Gelest"/>
: <math>\mathrm{H_2Si(C_6H_5)_2 + 2 \ H_2O \xrightarrow[]{cat.}\ (HO)_2Si(C_6H_5)_2 \ + 2 \ H_2 }</math>

二苯基硅烷和单质[[硫]]反应，生成含有三个硅和三个硫的六元杂环化合物：<ref name="ZNaturf"/>
: <math>\mathrm{3 \ H_2Si(C_6H_5)_2 + 6 \ S \xrightarrow{} \  \ S_3(Si(C_6H_5)_2)_3 \ + 3 \ H_2S }</math>
