Abstract
1,273,822. Lactam-N-carboxylic acid chlorides. BADISCHE ANILIN- & SODA-FABRIK A.G. 24 Sept., 1969 [25 Sept., 1968], No. 46931/69. Heading C2C. Lactam-N-carboxylic acid chlorides having 5 to 13 ring members are prepared by reaction of a 1-aza-2-etherified hydroxy-2-cycloalkene-1-carboxylic acid chloride with a hydrogen halide. Exemplified products are the N-carboxylic acid chlorides of caprolactam, capryl lactam and laurolactam.
