Abstract
Gold N-heterocyclic carbene complexes, in conjunction with a silver salt, were found to efficiently catalyze the rearrangement of allylic acetates under both conventional and microwave-assisted heating. The steric hindrance of the ligand bound to gold was found crucial as only bulky ligands permitted the isomerization.
