Dichloro (diphenyl) silane is a chemical compound from the group of organosilicon compounds .
history
The preparation of dichloro (diphenyl) silane was first carried out in 1886 by A. Polis by reacting tetraphenylsilane with phosphorus pentachloride . Depending on the ratio of the two reactants, dichloro (diphenyl) silane and chloro (triphenyl) silane are formed .
Extraction and presentation
On an industrial scale, dichloro (diphenyl) silane is produced by the thermal reaction of elemental silicon with chlorobenzene using copper as a catalyst:
properties
