O. Kitagawa et al., BECKMANN REARRANGEMENT OF O-4-PENTENYL OXIME THROUGH N-BROMOSUCCINIMIDE-MEDIATED ACTIVATING PROCESS, Chemical and Pharmaceutical Bulletin, 45(1), 1997, pp. 32-35
Beckmann rearrangement of O-4-pentenyl oxime derivatives proceeds in g
ood yield under mild conditions through the formation of a cationic te
trahydrofuranium intermediate in the halocyclization reaction with N-b
romosuccinimide.
