Preparative Method
: reduction of phenyltrichlorosilane or phenyltriethoxysilane with lithium aluminum hydride in ether.
1,3
Purification
: distillation under nitrogen at room temperature and atmospheric pressure.
4
Handling, Storage, and Precautions
: flammable. Stable at room temperature in closed containers. Phenylsilane is capable of releasing hydrogen gas upon storage, particularly in the presence of acids, bases, or fluoride‐releasing salts.
5
Precautions should be taken to vent possible hydrogen buildup when opening vessels in which phenylsilane is stored.
