Solubility: very sol THF, CH2Cl2, toluene. Preparative Methods: see text. Purification: Kugelrohr distillation (50 °C/0.001 mbar) Handling, Storage, and Precautions: the free oxazaborolidine must be rigorously protected from exposure to moisture. The crystalline borane complex is more stable, and is the preferred form to handle and store this catalyst." @default.
