Abstract: AN IMPROVED PROCESS FOR PRODUCING A LACTAM COMPLEX WHICH MAY BE READILY CONVERTED TO A CORRESPONDING LACTAM FROM AN ALICYCLIC KETOXIME COMPLEX BY REACTING SAID KETOXIME COMPLEX WITH A LACTIME-O-SULFONIC ACID METAL COMPOUND, AS A REARRANGEMENT REAGENT, OF THE FOLLOWING FORMULA (2)

(-O-SO2-O-C
WHEREIN R1 IS AN ALKYLENE GROUP SUBSTITUTED ALKYLENE GROUP HAVING 3 TO 11 CARBON ATOMS IN THE MAIN CHAIN, M IS A METAL ATOM SELECTED FROM METALS OF GOUPS 11B, IIIA, IV AND VA OF THE PERIODIC TABLE, X IS A HALOGEN ATOM, N IS THE MAXIMUM VALENCY OF M AND IS A POSITIVE INTEGER OF 2 TO 5, AND P IS EQUAL TO N OR A POSITIVE INTEGER SMALLER THAN N.
