Usage

General Description

TRIS(TRIMETHYLSILYL)GERMANIUM HYDRIDE, also known as germane trimethylsilyl derivative, is a chemical compound with the formula (CH3)3SiGeH3. It is a colorless and highly volatile liquid that is used as a precursor for the synthesis of various germanium-containing compounds. TRIS(TRIMETHYLSILYL)GERMANIUM HYDRIDE is commonly used in the semiconductor industry as a source of germanium for thin film deposition and as a dopant for the controlled modification of material properties. It is also used in organic synthesis and as a reagent in certain chemical reactions. TRIS(TRIMETHYLSILYL)GERMANIUM HYDRIDE is highly flammable and poses a significant risk of fire and explosions, requiring careful handling and storage.

Anionic Cadmium Complexes Containing the Bulky Tris(trimethylsilyl)germyl and Tris(trimethylsilyl)silyl Ligands

The first triiodo-bridged tris(trimethylsilyl)silyl- and tris(trimethylsilyl)germyldicadmium anionic complexes were prepared from CdI2 and 2 equiv of LiE(SiMe3)3 (E = Si and Ge) in hexane. The crystal structure of the germyl derivative 1 was determined. It crystallizes as a lithium salt from pentane in the Cmcm space group (orthorhombic) with a = 14.494(2), b = 16.334(3), and c = 27.361 ?, V = 6478 ?3, and Z = 4. The complex anion of 1, [(Me3Si)3GeCd(μ-I3)CdGe(SiMe 3)3-], exhibits two approximately tetrahedrally coordinated cadmiums with three iodides in trigonal bridging positions between the cadmiums. Efforts to prepare similar chloride-bridged structures were not fruitful.

Thermal and photochemical reactions of phenylethynyltris-(trimethylsilyl) germane

The thermal and photochemical behavior of phenylethynyltris(trimethylsilyl) germane (1) has been reported. The thermolysis of 1 in the absence of a trapping agent in a sealed glass tube at 240 °C for 6 h gave 1,3-bis(trimethylsilyl) -1-tris(trimethylsilyl)germyl-1-germaindene (2) in 18% yield, together with phenyl(trimethylsilyl)acetylene in 60% yield. Similar thermolysis of 1 in the presence of 2,3-dimethylbutadiene afforded 3,4-dimethyl-1,1-bis(trimethylsilyl)- 1-germacyclopent-3-ene (3) in 62% yield, along with phenyl(trimethylsilyl) acetylene. When 1 was irradiated with a low-pressure mercury lamp in the presence of a large excess of 2,3-dimethylbutadiene at room temperature for 10 min, compound 3 was obtained in 11% yield, in addition to 17% of phenyl(trimethylsilyl)acetylene and 31% of the starting compound 1. The photolysis of 1 in the absence of a trapping agent under the same conditions afforded phenyl(trimethylsilyl)acetylene as the sole volatile product. The DFT calculations were carried out to investigate the reaction mechanisms for the thermal reaction of 1 leading to the germaindene 2.

Preparation and structural characterization of trimethylsilyl-substituted germylzinc halides, (Me3Si)3GeZnX (X = Cl, Br, and I) and silylzinc chloride, R(Me3Si)2SiZnCl (R = SiMe3 and Ph)

The trimethylsilyl-substituted germylzinc halides, (Me3Si) 3GeZnX (X = Cl, Br, and I), and silylzinc chlorides, R(Me3Si)2SiZnCl (R = SiMe3 and Ph) have been prepared and their molecular structures have been full determined by spectroscopic and single-crystal X-ray diffraction methods. The germylzinc halides and silylzinc chlorides have dimeric structures consisting of two μ-halogen atoms. The reactivity of germylzinc chloride with substrates is also examined.
