Preparation of substituted lactams

Preparation of substituted lactams Ia to Ic STR1 where n is 0 or 1, X is --O--CO--R1, --O--SO2 --R1, --CO--R2, --CO--O--R3 or --CO--NR4 R5, R1 is a C1 -C8 -radical of a carboxylic or sulfonic acid, R2 is C1 -C8 -alkyl, R3 is H or alkyl, aryl or aralkyl of not more than 8 carbon atoms, R4 and R5 are each H or C1 -C4 -alkyl or together form a 5-membered or 6-membered ring, by reacting a lactam II STR2 with a vinyl compound III and a compound IV which forms free radicals to give Ia, and preparation of Ib by hydrolysis of a compound Ia in which X is (--O--CO--R1) or (--O--SO2 --R1), and preparation of Ic by thermolysis of Ib or of a compound Ia in which X is (--O--CO--R1) or (--O--SO2 --R1), and the novel substituted lactams Ia and Ib where X is (--O--CO--R1) and (--O--SO2 --R1).
