Mo(CO) 3 (NC t Bu) 3 (MoBI 3 ) was found to be a suitable catalyst for the regioselective hydrostannation of several types of alkynes, preferentially giving rise to the α‐stannylated products. These products are not available under radical reaction conditions, or by using other metal catalysts. This protocol tolerates a wide range of functional groups, and can also be applied to sensitive substrates, which cannot be hydrometallated with the commonly used palladium catalysts.
