Interconversion of silylphenyl and phenylsilyl cations in the reaction with benzene
Shishigin,Avrorin,Kochina,Sinotova,Ignat'ev
, p. 1393 - 1394 (2005)
The possibility for positive charge migration in SiC6H 7 + cation from carbon to silicon (or vice versa) was studied by the radiochemical method. Silylphenyl cation with initial charge localization on the carbon atom is transformed into phenylsilylium ion where the positive charge is localized on the silicon atom. No migration of positive charge from the silicon atom to carbon occurs. 2005 Pleiades Publishing, Inc.
Palladium(II) catalysed silicon-oxygen bond formation versus rearrangement reactions
Purkayastha,Baruah
, p. 9 - 14 (2001)
Phenylsilane and diphenylsilane undergoes rearrangement reactions by palladium catalysts such as Pd(TMEDA)Cl2, Pd(TEEDA)Cl2, [Pd(PPh3)]2Cl2 (where TMEDA = tetramethylethylenediamine, TEEDA = tetraethylethylenediamine) at room temperature. However, the reductive Si-O bond forming reaction can be performed on hydrosilanes through competitive paths. The reactions of phenylsilane and quinonic compounds are catlaysed by Pd(TMEDA)Cl2 (such as 1,4-benzoquinone, 1,4-napthoquinone) to give siloxanes, backbone of these siloxanes which contains rearranged phenylsilane units. The thin films of such oligomers has plot of resistance vs temperature profile resembling semiconductor.

-
Page/Page column 54; 57, (2021/12/08)
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.
CATALYTIC REDUCTION OF HALOGENATED CARBOSILANES AND HALOGENATED CARBODISILANES
-
Paragraph 0070; 0071, (2021/04/02)
Selective reduction methods for halogenated carbosilanes and carbodisilanes are disclosed. More particularly, high yields of the desired carbosilanes and carbodisilanes are obtained by reduction of their halogenated counterparts using a reducing agent and tetrabutylphosphonium chloride (TBPC) as a catalyst.
