Nature:
1. di-tert-butyldichlorostannane has good solubility, soluble in organic solvents such as ether, acetone and dimethylformamide.
2. It can be oxidized to di-tert-butyl tin dioxide, which can thermally decompose at high temperatures.
3. di-tert-butyldichlorostannane has a certain degree of stability, but it will gradually decompose under sunlight.
Use:
1. di-tert-butyldichlorostannane is commonly used as a reagent in organic synthesis and can be used as a solvent, catalyst and crosslinking agent.
2. It can be used in the rubber industry to cross-link neoprene and styrene butadiene rubber.
3. di-tert-butyldichlorostannane can also be used for halogenated hydrocarbon activation reaction and coupling reaction in organic synthesis.
Method:
The preparation method of di-tert-butyldichlorostannane is usually to react dimethyl tin with three other substances of tert-butyl ammonium chloride in ethanol, and then hydrolyze to obtain the product.
Safety Information:
1. di-tert-butyldichlorostannane has low toxicity, direct contact with skin and eyes should still be avoided.
2. During use, attention should be paid to prevent the substance from contacting the fire source and high temperature to avoid combustion or explosion accidents.
3. Keep away from flammable substances and oxidizing agents to avoid safety risks caused by improper storage and handling.
4. Wear protective gloves, goggles and protective clothing when using the substance. In the event of inadvertent contact or inhalation of the substance, immediately rinse the affected area thoroughly from a place where fresh air is readily accessible and seek medical advice.
