Usage

General Description

4-Triethoxysilylaniline is a chemical compound that is a silane coupling agent used in the production of various polymers and materials. It consists of a triethoxysilyl group attached to an aniline group, which makes it suitable for enhancing the adhesion and compatibility between organic materials and inorganic surfaces. This chemical is commonly used as an additive in the production of silylated polymers, coatings, adhesives, and sealants. It acts as a surface modifier, improving the bonding and durability of materials such as plastics, glass, and metals. Additionally, 4-Triethoxysilylaniline has potential applications in the field of biomedicine and as a surfactant in various industrial and consumer products.

Improved synthesis of aryltriethoxysilanes via palladium(O)-catalyzed silylation of aryl iodides and bromides with triethoxysilane

The scope of the palladium-catalyzed silylation of aryl halides with triethoxysilane has been expanded to include aryl bromides. A more general Pd(0) catalyst/ligand system has been developed that activates bromides and iodides: palladium(O) dibenzylideneacetone (Pd(dba)2) is activated with 2-(di-tert-butylphosphino)biphenyl (Buchwald's ligand) (1:2 mol ratio of Pd/phosphine). Electronrich para- and meta-substituted aryl halides (including unprotected aniline and phenol derivatives) undergo silylation to form the corresponding aryltriethoxysilane in fair to excellent yield; however, ortho-substituted aryl halides failed to be silylated.
