  • Cryosolvent. Has been proposed as a chlorine-free alternative solvent to dichloromethane in two-phase, including acylation and phase transfer alkylation, reactions. The water-saturated system (ca 39 mL/L) is more polar than the dry solvent, and it forms a useful azeotrope with water (ca 9 : 1), facilitating drying: Synlett, 2353 (2003).
