The Pt‐catalyzed hydrosilylation of alkynes is the procedure of choice to obtain vinylsilanes, and is claimed to be the most relevant application of Pt in organicsynthesis. More than half a century after its discovery, only β‐vinylsilanes (anti‐Markovnikov addition) are obtained with simple Pt catalysts, whereas α‐vinylsilanes (Markovnikov addition) remain elusive compounds. Here the catalysis of
