Substitution in the glutaconaldehyde anion takes place at C 2 or 4, demonstrated by deuterium exchange and by preparation of the mono- and dichloro or bromo and the monoiodo glutaconaldehyde sodium salts and their respective enol esters. The stable 2-iodoglutaconaldehyde was suggested to have the all-trans structure of 2-iodo-5-hydroxy-trans-2, trans-4-pentadienal. The preparations from the monochloro
戊二醛阴离子的取代发生在C 2或4,这是通过氘交换以及通过制备单氯和二氯或溴以及单碘戊二醛钠盐和它们各自的烯醇酯来证明的。建议稳定的2-碘戊二醛具有2-碘-5-羟基-反式-2,反式-4-戊二烯醛的全反式结构。由3-卤代吡啶的一氯和溴代戊二醛阴离子和噻吩-2-羧醛的制备物已被重新研究。
