Transition‐metal‐free hydrogenation of alkenes can be carried out with simple organocalcium catalysts (20 bar H 2 , 20 °C). Both steps in the proposed catalytic cycle, hydride addition to the double bond and σ‐bond metathesis with H 2 , have been confirmed. Alkenes sensitive to polymerization are also hydrogenated in good yields.
