Some Aspects of Chemistry of the N->Si Chelated Aryloxydihydrosilanes R(ArO)SiH2(R = Ph, ArO) and of the 2,2-Diaryloxytrisilane (Me3Si)2Si(OAr)2{ArO = 2,4,6-[(CH3)2NCH2]3C6H2O}

Reactions of the pentacoordinate aryldioxydihydrosilane Ph(Ar)SiH2 (1) with hydroxyl groups, carbonyl derivatives and PCl5 resulted in formation of new alcoxylated, phenoxylated and halogenated hydrosilanes Ph(ArO)(H)X (X = Cl, OR, OAr, OC(O)R), respectively. Treatment of the hexacoordinated (4+2) diaryloxydihydrosilane (ArO)2SiH2 (2) with N-chloro- or N-bromosuccinimide, trimethylsilyltriflate or iodine yielded the novel stable silicenium ion [(ArO)2(H)Si](1+)X(1-). Reactions of 2 with sulfur S8 and the transition metal complex Fe(CO)5 have resulted in the isolation of the new complexes (ArO)2Si = E [E = S, Fe(CO)4]. Decomposition modes of the tetracoordinate 2,2-diaryloxytrisilane (Me3Si)2Si(OAr)2 (3) on thermolysis and photolysis have also been studied; two pathways involving formation of the two silylenes (ArO)(Me3Si): and (ArO)2Si: have been identified by trapping experiments
L'electrosynthese, une voie simple d'acces aux di- et polysilanes

Electrochemical reduction of chlorosilanes, at constant current intensity, in a single compartment cell fitted with a sacrificial aluminium anode, is a practical and convenient route to di-, tri-, and poly-silanes.

1: 2-Adducts from Silylenes and 1,3-butadiene
Bobbitt, Kevin L.,Gaspar, Peter P.
, p. 17 - 26 (1995)
Photochemical generation of dimethylsilylene, methyl(phenyl)silylene and diphenylsilylene in the presence of high concentrations of 1,3-butadiene leads to the formation of 1-sila-3,4-divinylcyclopentanes as major products in addition to the anticipated 1-silacyclopent-3- enes.Also obtained are the ene-reaction products from the silenes, formed by formal 1,3-silyl shifts in the bis(trimethylsilyl)arylsilanes that are employed as the photochemical precursors of MePhSi: and Ph2Si:.Evidence is presented that both the divinylsilacyclopentanes and the silacyclopent-3-enes arise from vinylsilirane intermediates that can be trapped by acetone, yielding stable 3,3-dimethyl-4-vinyl-1- sila-2-oxolanes.Keywords: Silicon; Silylene

Attenuation of Ni(0) Decomposition: Mechanistic Insights into AgF-Assisted Nickel-Mediated Silylation
Balakrishnan, Venkadesh,Chindan, Bincy,Murugesan, Vetrivelan,Rasappan, Ramesh

In nickel-mediated Kumada cross-coupling reactions, low valent active nickel complexes are often generated in situ and the ligands usually govern the reactivity or stability of these complexes. However, the decomposition of active nickel complexes is inev

Paragraph 0013-0028, (2018/03/01)
The invention discloses a synthesis method of hexamethyl disilane and relates to a chemical process. The synthesis method includes: at the absence of oxygen, heating and stirring the inside of a reaction kettle added with xylene, crown ether and metal sodium, and dropwise adding trimethyl chlorosilane into the reaction kettle; after finishing, controlling temperature in the reaction kettle, holding the temperature, dropwise adding water into the reaction kettle when the temperature in the reaction kettle is lowered to 50+/-5 DEG C, and standing for layering; distilling for dehydration throughan oil-water separator to obtain a crude product-hexamethyl disilane. With the participation of the crown ether, metal sodium is used to react with trimethyl chlorosilane, so that electric potential of metal sodium is changed, activity of metal sodium is improved, and yield of the crude product can reach 73.17%. The synthesis method is simple and easy to control and convenient for industrial production.
