Organic Silicone , normally Chemical Organic Silicium which is known as Organic Silicone Chemicals, or Organosilicone Chemicals, are silicone compounds that contain Si-O bonds and have at least one organic group directly connected to a silicon atom.
Organic Silane / Silane Chemicals , or Organic Silane Chemicals the compound of silicon and hydrogen, is a general term for a range of Silicide Chemicals compounds, including silane (SiH4), ethyl silane (Si2H6) and some more advanced silicon hydrogen compounds.
Tetravinyltetramethylcyclotetrasiloxane is colorless transparent liquid, it can be miscible with most organic solvents and unsoluble in water.
VMC and aryl bromide will take rapid cross-coupling reaction, with the participation of tetrabutylammonium fluoride and palladium catalyst, coupling of ethylenes can be obtained. And it can be used as cross-linking agent or intermediate for vinyl methyl silicone rubber, high vinyl content silicone fluid, addition type silicone rubber, liquid silicone rubber, etc.
