Gold-catalyzed olefin cyclopropanation

The selectivity of the cyclopropanation of olefins with ethyl phenyldiazoacetate has been tested using different gold complexes bearing phosphine, phosphite or N-heterocyclic as ligands. A comparative study with related copper and silver complexes as catalysts is also presented. [Display omitted]
