[Uses]

(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.
