Allyltriphenylsilane is widely used in organic synthesis as a versatile reagent, particularly in the protection of alcohols and the formation of carbon-silicon bonds. It serves as a key intermediate in the preparation of complex organic molecules, including pharmaceuticals and agrochemicals. Its allyl group makes it valuable in cross-coupling reactions and as a precursor for allylic compounds. Additionally, it is employed in polymer chemistry to modify silicone-based materials, enhancing their properties for industrial applications. Its stability and reactivity also make it useful in catalytic processes and the development of advanced materials.
