Pd‐Catalyzed Cyclopropanation Reaction of Aliphatic Ketones with Monosubstituted Allyl Reagents

Abstract A Pd‐catalyzed cyclopropanation reaction with aliphatic ketones as nucleophiles using a modified pyridine‐NHC ligand was achieved. The reaction afforded the corresponding cyclopropanes in moderate to good yields with high cyclopropane/allylation selectivity.
