Substituted vinylsilanes

More commonly used than the parent vinylsilane are vinyl-substituted silanes with other substituents on silicon. In the area of organic synthesis, vinylsilanes are useful intermediates.[2]

Vinyltriethoxysilane is a common vinylsilane.

In the area of polymer chemistry and materials science, vinyltrimethoxysilane or vinyltriethoxysilane serve as monomers and coupling agents.

Preparation

Vinylsilanes are often prepared by hydrosilylation of alkynes. They can be made by the reaction of alkenyl lithium and Grignard reagents with chlorosilanes. In some cases dehydrogenative silylation is another method.[3]

gollark: Put a shape card into some slot or other of the shield projector.
gollark: RFTools can also do that.
gollark: Well, not a good one.
gollark: It's not a significant problem. Power is now never a significant balancing factor.
gollark: Oh, right.
