Aiming at improving catalyst activity, ten ruthenium promoters have been investigated in carbenoid transfer from ethyl diazoacetate to styrene as a model substrate. Optimal selectivity in cyclopropanation has been attained with the new NHC–Ru complex 10 , as well as with the Fischer carbene 7 . The surprising non‐metathetical behavior of the Grubbs’ first‐generation catalyst in this multifaceted process is highlighted. Copyright © 2014 John Wiley & Sons, Ltd.
