To and fro : Chiral metal–organic frameworks (CMOFs) derived from redox‐active ruthenium/salen building blocks exhibited reversible single‐crystal to single‐crystal reduction and reoxidation. The catalytically inactive Ru III CMOFs (green; see picture) were reduced to Ru II CMOFs (red) that were highly active for the asymmetric cyclopropanation of alkenes with very high diastereo‐ and enantioselectivities.
