Germanium—tungsten

Form complexes with titanium, germanium, tungsten 1630-1632... 

Analogous germanium-molybdenum, germanium-tungsten (145), germanium-cobalt (89), tin-cobalt, and lead-cobalt (144) carbene derivatives are known. 

In this process, the substrate is placed inside a reactor supplied by different gases [21], The principle of the process is that a chemical reaction takes place between the source gases producing a solid material which condenses on all surfaces inside the reactor. CVD is widely used in the semiconductor industry to deposit various materials such as polycrystalline, amorphous, and epitaxial silicon, carbon fiber, filaments, carbon nanotubes, Si02, silicon-germanium, tungsten, silicon nitride, silicon oxynitride, titanium nitride, and various high-k dielectrics. 

In addition to tungsten and molybdenum, the other metals produced by hydrogen reduction are germanium and rhenium.

While the germanium-containing tungsten complex 166 rearranged to 167 on photolysis, the isomeric species 168 directly eliminated the silene Me2Si=CH2 yielding 169 (Scheme 26)80.

In a third class of 7t-cyclopentadienyl complexes, compounds of type LVIII are bound to a transition metal via the lone pair at the germanium atom. The first compounds in this series, the pentacarbonyl-[chloro(pentamethylcyclopentadienyl)germylene]chromium(0) (LIXa) and -tungsten(O) (LIXb) were synthesized by alkylation of the ylide complexes (CO)5M—GeCl2 THF according to Eq. (22) (201). Nucleophilic substitution reactions of LIXb lead to the alkyl- and amino-substituted complexes LIXc-e [Eq. (23)] (202).
