The protected bromoaniline is then reacted with n-butyllithium and chlorodialkylsilane to form 1-((dialkylsilyl)phenyl)-2,2,5,5-tetramethyl-l-aza-2,5-disilacyclopentane. Next, the protected dimethylsilane aniline is subjected to de-protection to form aminophenyldialkyl silane, which is considered to be novel. This silane is then hydrolyzed to form the corresponding silanol, also considered to be novel. The silanol is then condensed to form bis(amino-phenyl)-1,1,3,3-tetraalkyldisiloxane.Type: GrantFiled: April 16, 1992Date of Patent: February 15, 1994Assignee: Hughes Aircraft CompanyInventor: Thomas K.
