title: Rhodium(III)-catalyzed transannulation of cyclopropenes with N-phenoxyacetamides through C-H activation.
abstract: An efficient rhodium(III)-catalyzed synthesis of 2H-chromene from N-phenoxyacetamides and cyclopropenes has been developed. The reaction represents the first example of using cyclopropenes as a three-carbon unit in rhodium(III)-catalyzed C(sp(2))-H activations.
