摘要: 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 cyclopropanation has attained with the new NHC–Ru complex 10, well Fischer carbene 7. The surprising non-metathetical behavior of Grubbs’ first-generation this multifaceted process is highlighted. Copyright © 2014 John Wiley & Sons, Ltd.
