CAS 124-70-9

Methylvinyldichlorosilane

Description:

Methylvinyldichlorosilane, with the CAS number 124-70-9, is an organosilicon compound characterized by its silane structure, which includes a methyl group, a vinyl group, and two chlorine atoms attached to a silicon atom. This compound is typically a colorless to pale yellow liquid with a pungent odor. It is known for its reactivity, particularly in polymerization processes, where it can participate in the formation of silicone polymers. Methylvinyldichlorosilane is soluble in organic solvents but reacts with water, releasing hydrochloric acid and forming silanol compounds. Due to its chemical properties, it is used in the production of silicone materials, coatings, and sealants. Safety precautions are necessary when handling this substance, as it can be corrosive and poses health risks through inhalation or skin contact. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and prevent unwanted reactions.

Alkenylsilane Cross-Coupling Agent
The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.
