A matter of convenience: Schrock molybdenumalkylidenes are amongst the most powerful olefin metathesis catalysts known to date, but their sensitivity to air and moisture mandates their handling in a glove‐box or by Schlenk techniques. This inconvenience is circumvented by using the corresponding phenanthroline‐ or bipyridine adducts, which are bench‐stable and hence very user‐friendly. The active
