Diphenylsilanediol , Ph 2 Si (OH) 2 , is a chemical compound and one of the silanols . The molecule has a tetrahedral geometry. In the solid state, it forms hydrogen bonds .
Manufacturing
Diphenylsilanediol can be prepared from diphenyldichlorosilane by hydrolysis .
The action of phenyllithium on silica gel results in tetraphenylsilane and triphenylsilanol as well as diphenylsilanol.
use
Diphenylsilanediol can be used as an anticonvulsant . It works similarly to phenytoin .
