• A new method for the hydrosilylation of alkynes controlled by a platinum catalyst with a monophosphine ligand (called TBSO‐MOP) was explored. The platinum‐catalyzed multicomponent and sequential silylation reaction involving alkynes, alcohols, and dihydrosilanes resulted in the highly stereoselective and high‐yielding construction of functional (E)‐vinylsilyl ethers. Moreover, the one‐pot bis‐hydrosilylation of terminal alkynes with dihydrosilanes was also achieved with the same platinum catalyst system. Controllable hydrosilylation: The powerful potential of a monophosphine ligand bearing a silicon‐based bulky group, called TBSO‐MOP, in the chemoselectivity‐controllable platinum‐catalyzed multicomponent hydrosilylation of alkynes with dihydrosilanes is revealed. (E)‐Vinylsilyl ethers and di‐(E)‐vinylsilanes are obtained in high yields from internal and terminal alkynes, respectively. dba=dibenzylideneacetone.
