As a new and complementary method for the synthesis of structurally defined tetrasubstituted alkenes, a copper‐catalyzed regio‐ and anti‐selectiveaddition of silylboronates to unsymmetric internal alkynes has been developed. A variety of unactivated alkynes can be employed with high selectivity under simple and mild conditions, and the resulting products have been further functionalized by utilizing
