Reactions of 2-oxo-2-dialkylamino-1,2-oxaphospholanes with acid chlorides
摘要:
The reaction of acetyl chloride, chloroacetyl chloride, benzoyl chloride, and phosphorus trichloride with 2-oxo-2-dialkylamino-1,2-oxaphospholanes gives 2-oxo-2-chloro-1,2-oxaphospholanes. Phosphorus pentachloride opens the 1,2-oxaphospholane ring with the formation of dimethylamido-3-chloroalkylphosphonyl chloride.
