, p. 12010 - 12017 (2015/01/09)
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 affo
Cyclopropanation of Ester Enolates by ?-Allylpalladium Chloride Complexes
Hegedus, Louis S.,Darlington, W.H.,Russell, Charles E.
, p. 5193 - 5196 (2007/10/02)
Branched ester enolates react with ?-allylpalladium chloride complexes in the presence of Et3N and HMPA to produce alkylated cyclopropanes.Labeling studies indicate the carbanion attacks the central carbon of the ?-allyl complex.
