    摘要: THE PRODUCTION OF LACTAM-N-CARBOXYLIC ACID CHLORIDES HAVING 5 TO 13 RING MEMBERS BY REACTING WITH A HYDROGEN HALIDE A 1-AZA-2-HYDROXYCYCLOALKENE-(2)-CARBOXYLIC ACID CHLORIDE-(1) WHICH IS ETHERIFIED IN THE 2-POSTION. LACTAMN-CARBOXYLIC ACID CHLORIDES ARE SUITABLE FOR THE PRODUCTION OF N-SUBSTITUTED LACTAMS FROM WHICH THE CORRESPONDINGLY SUBSTITUTED POLYAMIDES MAY BE PRODUCED.
