Base-Promoted Tautomerization of Imidazole Ligands to N-Heterocyclic Carbenes and Subsequent Transmetalation Reaction
摘要:
Imidazole complexes of manganese(I) are transformed into their corresponding N-heterocyclic carbene derivatives by means of acid-base treatments; the subsequent sequential transmetalation reaction of the carbene to gold(I) proceeds through isolable heterometallic intermediate species.
