Usage

General Description

Dimethyldiphenylsilane, also known as diphenyl(dimethyl)silane, is a chemical compound with the molecular formula C14H16Si. It is a colorless liquid with a faint sweet odor. Dimethyldiphenylsilane is used as a silane coupling agent in polymer and surface modification reactions. It can also be used as a crosslinking agent in the formulation of silicone rubber and other silicone-based materials. Additionally, it is utilized as a reducing agent in organic and inorganic synthesis reactions. DIMETHYLDIPHENYLSILANE is flammable and should be handled with proper precautions to avoid potential hazards.

A nickel-catalyzed silylation reaction of alkyl aryl sulfoxides with silylzinc reagents

Ni(PEt3)Cl2-catalyzed silylation of alkyl aryl sulfoxides with silylzinc reagents was carried out. This protocol allows alkyl aryl sulfoxides to convert to arylsilicon compounds under mild reaction conditions, tolerates a range of functional groups and is suitable for a wide scope of substrates.

Hydrogenolysis of Polysilanes Catalyzed by Low-Valent Nickel Complexes

The dehydrogenation of organosilanes (RxSiH4?x) under the formation of Si?Si bonds is an intensively investigated process leading to oligo- or polysilanes. The reverse reaction is little studied. To date, the hydrogenolysis of Si?Si bonds requires very harsh conditions and is very unselective, leading to multiple side products. Herein, we describe a new catalytic hydrogenation of oligo- and polysilanes that is highly selective and proceeds under mild conditions. New low-valent nickel hydride complexes are used as catalysts and secondary silanes, RR′SiH2, are obtained as products in high purity.
