Fis(c)hing for cyclization! The sequential treatment of an acetylide with a Fischer carbene complex and an alkene/diene yields alkynylcyclopropanes with a wide substitution range. The intramolecular process provides 1‐alkynylbicyclo[3.1.0]cyclohexanes by starting from 1,6‐enynes. A non‐heteroatom‐stabilized metal alkynylcarbene is responsible for the selective transfer of the propargylene unit.
