Usage

General Description

N-Octylsilane is a chemical compound featuring an eight-carbon alkyl chain attached to a silicon atom. It is a colorless, flammable liquid that is used as a coupling agent and surface modifier in various industrial applications. N-octylsilane is also utilized in the production of silicone compounds, and as a coating and adhesion promoter in the manufacture of plastics, rubbers, and adhesives. It can also function as a hydrophobic agent, providing water repellent properties to surfaces and materials. Additionally, it is important to handle n-octylsilane with caution, as it poses flammability and health hazards, and should be stored and used in a well-ventilated area with appropriate safety measures in place.

PROCESS FOR THE STEPWISE SYNTHESIS OF SILAHYDROCARBONS

The invention relates to a process for the stepwise synthesis of silahydrocarbons bearing up to four different organyl substituents at the silicon atom, wherein the process includes at least one step a) of producing a bifunctional hydridochlorosilane by a redistribution reaction, selective chlorination of hydridosilanes with an ether/HCI reagent, or by selective chlorination of hydridosilanes with SiCI4, at least one step b) of submitting a bifunctional hydridochloromonosilane to a hydrosilylation reaction, at least one step c) of hydrogenation of a chloromonosilane, and a step d) in which a silahydrocarbon compound is obtained in a hydrosilylation reaction.

Formal SiH4 chemistry using stable and easy-to-handle surrogates

Monosilane (SiH4) is far less well behaved than its carbon analogue methane (CH4). It is a colourless gas that is industrially relevant as a source of elemental silicon, but its pyrophoric and explosive nature makes its handling and use challenging. Consequently, synthetic applications of SiH4 in academic laboratories are extremely rare and methodologies based on SiH4 are underdeveloped. Safe and controlled alternatives to the substituent redistribution approaches of hydrosilanes are desirable and cyclohexa-2,5-dien-1-ylsilanes where the cyclohexa-1,4-diene units serve as placeholders for the hydrogen atoms have been identified as potent surrogates of SiH4. We disclose here that the commercially available Lewis acid tris(pentafluorophenyl)borane, B(C6F5)3, is able to promote the release of the Si-H bond catalytically while subsequently enabling the hydrosilylation of C-C multiple bonds in the same pot. The net reactions are transition-metal-free transfer hydrosilylations with SiH4 as a building block for the preparation of various hydrosilanes.
