Usage

General Description

Triisopropylchlorogermane is an organogermanium compound with the chemical formula C9H21ClGe. It is a colorless, flammable liquid with a strong, unpleasant odor. It is used in the synthesis of various organogermanium compounds, as a catalyst in organic reactions, and as a reagent in organic chemistry. It is highly reactive and should be handled with care, as it can react violently with water, air, and oxidizing agents. Triisopropylchlorogermane is also used in the semiconductor industry as a precursor for the deposition of germanium-containing thin films in the production of electronic devices. It is important to handle and store this chemical properly to avoid any potential hazards.

A series of isopropyl-substituted oligogermanes Pri3Ge(GePh2)nGePri3 (n = 0-3) featuring a luminescent and dichroic pentagermane Pri3Ge(GePh2)3GePri3

The series of oligogermanes Pri3Ge(GePh2)nGePri3 (n = 0, 2; n = 1, 3; n = 2, 4; n = 3, 5) were prepared by the hydrogermolysis reaction. All four species were characterized by NMR (1H and 13C) and UV/visible spectroscopy as well by cyclic voltammetry and differential pulse voltammetry. The oligogermanes exhibited a successive red shift in their absorbance maxima as the length of the Ge-Ge chain was increased, and these molecules also became easier to oxidize as the chain length was increased. The X-ray crystal structures of 4 and 5 as well as the trigermane HPh2GeGePh2GePh2H (6) were determined. The pentagermane 5 was shown to be dichroic in the solid state due to the packing of the individual molecules in a columnar fashion in the crystal. Pentagermane 5 is also luminescent in solution, exhibiting an emission maximum at 380 nm. The physical properties of 5, like the hexagermane Pri3Ge(GePh)4GePri3, mimic the properties of the larger polygermane systems.

Ethynylisopropylgermanes and their trimethylsilyl derivatives

The reaction of ethynylmagnesium bromide with chloroisopropylgermanes (i-Pr4-nGeCln, n = 1-3) was used to prepare previously unknown ethynylisopropylgermanes i-Pr4-nGe(C≡CH)n (n = 1-3). The reaction of Me3

Preparation of stable compound with O-Hg-Ge grouping

1. The first stable compound with an O-Hg-Ge grouping was obtained by the reaction of 4,6-ditert-butyl-1,2-benzoquinone with bis(triisopropylgermyl)mercury. 2. A study was made of the photodecomposition of 1-triisopropylgermyloxy-2-triisopropylgermyl-mercuroxy-3,5-di-tert-butylbenzene, and also of its reaction with hydrochloric acid and ethylmercury chloride.
