Strong 15N nuclear polarisation is present in both the uncatalysed and acid-catalysed rearrangements of 4-methyl-4-nitrocyclohexa-2,5-dienone but is absent from the rearrangement of 2-methyl-2-nitrocyclohexa-3,5-dienone.
在未催化的和酸催化的4-甲基-4-硝基环六-2,5-二烯酮重排中均存在强15 N核极化,但在2-甲基-2-硝基环六-3,5-二烯酮的重排中不存在强15 N核极化。 。
