The cyclic alkyl(amino) carbene (cAAC) [:C{N-C6H3(2,6-IPr2)}(CMe2)2CH2] stabilized MeGeGeMe has been isolated in the molecular form with composition (cAAC)MeGe-GeMe(cAAC) (1) at room temperature. Compound 1 was synthesized from the reduction of MeGeCl3 using three equivalents of KC8 in the presence of one equivalent of cAAC. The corresponding silicon compound (cAAC)MeSi-SiMe(cAAC) (2) was also ...

The stereochemistry with which allylsilanes react with electrophiles is reviewed. Stereochemically defined allylsilanes (14 and 15) can be prepared by the stereospecific anti displacement of tertiary allylic acetates (9-12) with the phenyldimethylsilyl-cuprate reagent (13). These allylsilanes react with electrophiles with an overall anti bias. In protonation (Scheme 13) and especially in acylat...

Particulate contamination formed by homogeneous clustering reactions of silicon hydrides within silicon chemical vapor deposition processes is an important source of yield loss during semiconductor processing. On the other hand, intentional synthesis of silicon nanoparticles may be of great interest because of the unique optical and electronic properties of nanostructured silicon. Kinetic model...

The n + CdS-nCdS-nSi structures were obtained, and their volt-ampere characteristics at different temperatures studied. dependence of the characteristic shows that sublinear quadratic section these has a current growth with voltage. It is determined in flow direction low illumination levels work as an injection photodiode. And under laser λ=0.625 μm power P=1.2 µW/cm 2 have spectral sensitivity...

The crystal structure of Ci2HiiN2SiCl3 (monoclinic, P2i/m, Z = 2, with a: 9.284(4), b: 7.226(2), c: 10.832(5) Ä, ß = 115.14(3)°) was refined to R(F) 0.035 from 1228 independent reflections. A trigonal bipyramidal, pentacoordinate silicon is observed. The chelated complex shows two different Si-N bonds, a coordinative bond (1.984(2) A) between Si and N on the axial position and a Si-N single bon...
