Description

Application

(4-Chlorophenyl)triethoxysilane can be used:

• To facilitate the connection between dipolar mixed monolayers and zinc oxide in photovoltaic devices.
• As a substrate in the Ni-catalyzed decarboxylative coupling with alkynyl carboxylic acids to yield substituted diarylalkynes.
• As a substrate in the Hiyama cross-coupling reactions with 3-iodoazetidines to yield substituted 3-arylazetidines.
• As an intermediate in the synthesis of tripod-shaped oligo(p-phenylene)s, which are used in the surface immobilization of gold and CdS quantum dots for sensor applications.
