3-PHENYLHEPTAMETHYLTRISILOXANE Usage And Synthesis

Uses

Arylsilanes, such as 1,1,1,3,5,5,5-heptamethyl-3-phenyltrisiloxane, are compounds used in the organosilicon chemical industry. Various synthetic methods have been proposed to date. For example, Grignard reagents and aryllithium are known to be prepared from aromatic halides, followed by coupling reactions with halosilanes. Other methods include the reaction of aromatic halides with hydrosilanes using palladium catalysts, the reaction of aromatic hydrocarbons with hydrosilanes using rhodium catalysts, the reaction of benzo[a]trifluoride with hydrosilanes using rhodium catalysts, and the reaction of benzene with hydrosilanes using platinum catalysts.
