Tetraphenylsilane is a chemical compound from the group of carbosilanes .
Extraction and presentation
Tetraphenylsilane was first produced in 1886 by A. Polis by the simultaneous reduction of tetrachlorosilane and chlorobenzene with metallic sodium in diethyl ether .
It can also be obtained by reacting phenyllithium with silicon chloride.
It is also produced by the decomposition of octaphenylcyclotetrasilane .
properties
Tetraphenylsilane is a white solid that is insoluble in water. It is so stable that it can be distilled at a temperature of 550 ° C without decomposition. It is difficult to use in diethyl ether and ethanol , and easily soluble in hot benzene .
