Process for the preparation of 1-oxo-phospholane-chloro-hydrins

摘要

1-Oxo-phospholane-chlorohydrins are prepared by reacting 1-oxo-phospholenes with chlorine in the presence of bases which bond hydrogen chloride in a molar ratio of about 1:1:1 in water; the water is optionally in mixture with a water-miscible inert organic solvent. Most of the reaction products are new compounds, which are chiefly used as intermediate products in the field of plastics, of hydraulic fluids and of catalysts for converting isocyanates into carbodiimides.
