Patent ID: 8299263

Claim:
An N-Heterocyclic carbene-amido palladium(II) catalyst having a chemical structure according to general formula I: wherein R 1 and R 5 may be the same or different and are selected from the group consisting of H, alkyl of 1 to 10 carbon atoms, aryl of 1 to 10 carbon atoms, and aralkyl of 1 to 10 carbon atoms, and may optionally contain one or more heteroatoms; R 2 is selected from the group consisting of H, alkyl of 1 to 10 carbon atoms, aryl of 1 to 10 carbon atoms, and aralkyl of 1 to 10 carbon atoms, or optionally forms part of a linkage to form a dimer; R 3 and R 4 is selected from the group consisting of H and an aryl ring of from 4 to 8 carbon atoms; R 6 is selected from the group consisting of H and alkoxy having 1-4 carbon atoms; and L is selected from the group consisting of a halogen or optionally forms part of a linkage to form a dimer, wherein the linkage from R 1 to the ring carbon is either chiral or achiral, and wherein the chemical structure may be in a dimeric form.
