Divalent Silicon(0) Compounds

Chemistry – A European Journal, 2009
AbstractBridge of Si's: Quantum‐chemical calculations suggest that the bonding situation in the recently synthesized “trisilaallene” is better described in terms of donor–acceptor interactions between two silylene ligands L and a naked silicon atom Si, which carries two lone‐pair orbitals, yielding the silylone SiL2.

Pentacoordinate silicon compounds: Pseudorotation at silicon

Journal of Organometallic Chemistry, 1984
Abstract The variation with temperature of the 19 F and 1 H NMR spectra of pentacoordinate fluorosilanes which contain an intramolecular SiN coordination has been examined. A clear distinction between pseudorotation and ring opening-closing processes has been obtained for the first time and the corresponding activation energies determined.

Silicon compounds in biological systems

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1968
The part played by silicon compounds in terrestrial life can be discussed under three main headings. First is the important skeletal role which silica fulfils in organisms such as diatoms. Secondly is the reduction of silicate which can be performed by various micro-organisms and the question whether this can be regarded as a specific participation in ...

Isolable Compounds Containing a Silicon-Silicon Double Bond

Science, 1984
After 70 years of unsuccessful attempts, several stable disilenes—compounds with double bonds between silicon atoms—have now been made. The silicon-silicon double bond resembles in many ways the well-known carbon-carbon double bond of organic chemistry.

Organo-Silicon Compounds

1975
Infra-red absorption bands arising from linkages involving silicon atoms are about five times more intense than the bands from the corresponding carbon linkages. The reasons for this have been discussed by Wright and Hunter [1]. This fact is of considerable help in analytical work, and infra-red absorption spectra have been very extensively employed in

Silicone paints and compounds

Pigment & Resin Technology, 1985
Silicone in the form of a base for compounds and paints is increasingly being used in the marine industry as a bedding for deck fixtures, sealing instruments, galley fittings and as a general protective coating.
