Phenylheptamethyltrisiloxane - Reference Information

Uses

Aryl silanes such as 1,1,1,3,5,5, 5-heptamethyl-3-phenyltrisiloxane are used in the organosilicon chemical industry. Compounds in the chemical industry have been proposed so far, such as the known preparation of Grignard reagents from aromatic halides, aryl lithium, etc, and carry out the coupling reaction with halosilane. In addition, a palladium catalyst is used to react aromatic halides with hydrosilane, and a rhodium catalyst is used to irradiate light to react aromatic hydrocarbons with hydrosilane, a rhodium catalyst is used to react benzotrifluoride with hydrosilane, and a platinum catalyst is used to react benzene with hydrosilane.
