Application
Trichlorovinylsilane is a versatile chemical known for its ability to act as a crucial intermediate in the production of silicones and as a coupling agent in adhesives and bonds. This colorless or pale-yellow liquid is notable for its reactivity, readily hydrolyzing with the release of hydrogen chloride and polymerizing easily. It is soluble in most organic solvents and reacts with alcohols, which expands its utility across various applications. One notable use of trichlorovinylsilane is in biomedical research, where it has been explored for treating materials like Pluronic F127 and chitosan, enhancing the attachment and proliferation of endothelial cells on biomaterials. Additionally, it serves as a precursor in the preparation of epoxy-terminated carbosiloxane, illustrating its broad applicability in advanced material science.

Other Experimental
Reacts violently with water, moist air, or steam to produce toxic and corrosive fumes;Reacts with alcohol;Readily hydrolyzed, with liberation of hydrogen chloride; polymerizes easily;The reaction of organosilanes with halogens and halogen cmpd usually proceeds in good yield through cleavage of the Si--H bond and formation of the silicon-halogen bond. Reaction with fluorine, however, does not proceed satisfactorily because of cleavage of not only the Si--H but also C--Si and C--H bonds. Direct halogenation with chlorination, bromine, and iodine proceeds smoothly, however. /Organosilanes/
