Dirhodium tetrakis[N-phthaloyl-(S)-tert-leucinate] bis(ethyl acetate) adduct

The tetra[N-phthaloyl-(S)-tert-leucine]dirhodium-bis(ethyl acetate) adduct is an optically active chiral dirhodium complex (II) developed by Ryutaro Hashimoto and his colleagues. It is used as a catalyst to decompose diazo compounds into ylide configurations.
