Diadamantylsilylene and its stereochemistry of addition

Direct Gas-Phase Kinetic Studies of Silylene Addition Reactions: SiH2 + C3H6, SiH2 + i-C4H8, and SiMe2 + C2H4. The Effects of Methyl Substitution on Strain Energies in Siliranes

“…19 In addition, the loose transition states found here (even for SiMe 2 addition) are not in conflict with long known, concerted, stereospecific nature of the silylene addition process. 16,36 RRKM Calculations, Ab Initio Calculations, and Silirane Strain Energies. The reasonable fit of the RRKM calculations to the pressure dependencies of the experimental rate constants lends weight to the conclusion that the addition reactions 3, 4, and 5 investigated here are all straightforward third-body assisted association processes.…”

Synthesis of aminotri- and aminotetrasilanes by cross-coupling of aminochlorosilanes with chlorotrimethylsilane

“…They can easily be converted into the halogen derivatives 11, earlier obtained by chlorination [13] or by cleavage of phenyl groups with HX/AlX 3 [14][15][16], or into alkoxy derivatives. Thus, 9a or 9b reacted with excess HCl in ether at low temperature (0-5ЊC) to form the respective 2,2-dichloro-1,1,1,3,3,3-hexamethyltrisilane 11a with good yield.…”

Steric effects on the dialkyl substituted X2C2Si silylenes: A theoretical study

“…Chemical species which involve divalent silicon atoms, silylenes, are key intermediates in numerous thermal and photochemical reactions of organosilicon compounds [4]. Besides, much interest has been focused on their bonding properties and reactivities such as addition to olefins [11,12], alkynes [13], isocyanides [14], and transition metal complexes [15] in connection with the reactivities of carbenes. The multiple-bond compounds including second period elements such as olefin, imine (Schiff base), ketone, acetylene, nitrile, etc.…”
