from various substituted organic hydrazines and phenol aldehydes. The degree of conversion was increased by high electronic density on the amino group of the hydrazine reactant, as well as low steric hindrance around both reactive sites. In this particular case, the flexibility of the chain bearing the amino reactive site of hydrazine was highlighted as a factor influencing the reaction rate. The results
在振动球磨机中成功地由各种取代的有机肼和酚醛合成了一系列潜在的治疗剂azo。肼反应物氨基上的高电子密度以及两个反应位点附近的低位阻均提高了转化度。在这种特定情况下,带有肼的氨基反应位点的链的柔韧性被强调为影响反应速率的因素。结果表明,在不存在副产物的情况下,可以以超过99%的转化率获得。这高度适合于需要高纯度的活性药物成分的合成。
