Physical Data: mp >280 °C, (c 0.054, benzene), green solid.1 Solubility: sol in most organic solvents, sparingly sol in hexane. Form Supplied in: not commercially available. Preparative Methods: the reagent is prepared from dirhodium tetraacetate by ligand exchange with N-tetrachlorophthaloyl-(S)-t-leucine according to the method of Callot.1, 2 Purification: the title compound can be readily purified by column chromatography on silica gel using Et2O/benzene (1:15) as eluent followed by recrystallization from 1:1 hexane/EtOAc to provide the bis(ethyl acetate) adduct as green prisms.1 Handling, Storage, and Precautions: air stable but hygroscopic." @default.
