(3-Bromophenoxy)(tert-butyl)dimethylsilane is the tert-butyldimethylsilyl (TBDMS)-protected derivative of 3-bromophenol. The silyl ether serves as a protecting group for the phenolic hydroxyl, enabling selective reactions at the aryl bromide position, such as palladium-catalyzed cross-coupling (e.g., Suzuki-Miyaura, Sonogashira). This stability under basic and neutral conditions, with deprotection possible under mild acidic conditions, makes it valuable in multi-step organic synthesis, particularly for pharmaceuticals, agrochemicals, and advanced materials. The bulky TBDMS group provides steric hindrance, minimizing unwanted side reactions during assembly of complex molecules.
