Description
Summary:One handed is very efficient not only for fiddler crabs, but also for chiral ruthenium metathesis (pre)catalysts that contain a monosubstituted carbon center in the N‐heterocyclic ligand. In their Communication on page 3972 ff. S. Blechert and co‐workers show that through the combination of ligands a highly stable catalyst is formed that rapidly initiates the asymmetric ring‐opening cross‐metathesis and delivers high E‐isomer selectivity and high enantioselectivity.
