Carried on butterfly wings. The unsymmetrical air‐stable disilane, Me₃Si−SiMe₂[oCON(iPr)₂C₆H₄], bis‐silylates terminal alkynes to yield Z‐vinyl disilanes with high regioselectivity and good functional group tolerance. In their Communication (DOI: 10.1002/anie.201800513), Z. L. Song et al. describe a transformation that is difficult to achieve using traditional halide or methoxy‐substituted unsymmetrical disilanes; a metamorphosis of cocoon‐like alkynes into butterfly‐like Z‐vinyl silanes.
