title: Pyridine-NHC: effective ligand in Pd-catalyzed cyclopropanation of esters with substituted allyl carbonates.
abstract: By consideration of the mechanism of Pd-catalyzed cyclopropanation and allylation, NHC-pyridine compounds were adopted as the ligand in Pd-catalyzed cyclopropanation of esters and monosubstituted allylic reagents. The corresponding cyclopropanes were afforded as major products in moderate to good yields with high cyclopropane/allylation selectivity.
