Photoinduced electron-transfer reaction of 7,8- disilabicyclo[2.2.2]octa-2,5-dienes

9,10-Dicyanoanthracene-sensitized irradiation of 7,8- disilabicyclo[2.2.2]octa-2-5-dienes1-3 in the presence of MeOH resulted in the formation of dimethoxydisilanes and the corresponding aromatic compounds. A stepwise mechanism involving C-Si bond cleavage by MeOH is proposed.

Reaction of the Si-Cl bond with trialkyl orthoformates preparation of alkoxy-substituted silanes

Trialkyl orthoformates in the presence of aluminium chloride represent quite useful reagents to generate silicon alkoxides from chlorosilanes. 3-Cyanopropyltrichlorosilane and 2-[(2-trichlorosilyl)ethyl]-pyridine give the triethoxy compounds 3-cyanopropyltriethoxysilane and 2-[(2-triethoxysilyl)ethyl]-pyridine respectively. Via this route, in methylchlorooligosilanes a partial or complete exchange of the chlorine substituents for alkoxy groups occurs depending on the starting molar ratio of silane:HC(OR)3 (R = Me, Et). SiCl2Me groups react to SiClMe(OR) first before SiMe(OR)2 groups are formed. (Si)2SiClMe units are not affected by HC(OR)3.

Synthesis and reactions of silanes containing two triflate groups

1,2-Bis(trifluoromethanesulfonyloxy)tetramethyldisilane (1) and dimethylsilylbis(trifluoromethanesulfonate) (2) have been prepared via displacement of phenyl, chloro, and methyl groups in the corresponding mono- and di-silanes.Phenyl groups are displaced more rapidly than chloro and methyl groups.The unreacted groups are strongly deactivated by the presence of a triflate group at the same silicon atom.The deactivation is much weaker when a triflate group is present at the adjacent silicon atom.Alcohols and amines react more rapidly with ditriflates than with monotriflates.
