先前对三唑基N-杂环卡宾的三唑离子共轭酸的三唑离子共轭酸的C(3)-氢/氘交换反应的研究表明,在酸性条件下,随着N1质子化成药用盐,其机理发生了变化。有趣的是,数据表明,相对于其他具有氢或甲基取代基而不是邻位氟的N-芳基取代基,在存在N-五氟苯基取代基的情况下,p K a N1的增加。探测氮的明显供体效应的存在五氟苯基取代基不同于该组中更常见的吸电子效果,我们研究了四种三唑鎓盐与N-芳基的2位和/或6位杂原子或杂原子取代基的类似氘交换反应戒指。这些包括具有N -2,4,6-三溴苯基11,N -2,6-二氯苯基12,N -2-吡啶基13和N -2-嘧啶基14取代基的三唑盐。日志ķ前- P d为型材11,12和14与先前研究的N-五氟苯基三唑鎓盐相比,发现在较低的p D s处显示出相似的趋势,因此支持了对p K a N1的明显供体效应。令人惊讶的是,N-吡啶盐13的log k ex -p D曲线在较低的p

The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

A mildapproach to diazenylation of active methylene compounds and N-heterocyclic compounds with arylhydrazine hydrochlorides in the presence of iodine under basic aerobic conditions was developed. The reaction could be executed either under heating or in the presence of blue LED light, though the latter condition was found to be relatively efficient. Presumably, the aryldiazene produced by oxidation
