The addition of phenylhydrazine to phenylazo-alkenes 4 yields α-(1-phenylhydrazino)-phenylhydrazones 1. The reaction of phenylhydrazine with α-halogenated carbonyl compounds 5 affords either 1 or the isomeric α-(2-phenylhydrazino)-phenylhydrazones 2. Structures 1 and 2 (>N-NH2 and-NH-NH- groups, respectively) can be differentiated by 1H NMR in DMSO-D6 solution. Possible pathways of the reactions leading
将苯肼加到苯基偶氮-烯烃4中可得到α-(1-苯基肼基)-苯基hydr。苯肼与α-卤代羰基化合物5的反应可得到1或异构体α-(2-苯基肼基)-苯基hydr2。结构1和2(分别为> N-NH 2和-NH-NH-基团)可以通过DMSO-D 6溶液中的1 H NMR进行区分。讨论了导致1或2的反应的可能途径。发现化合物1是苯基osazones 6的前体。
