摘要
聚苯乙烯磺酰肼与醛或酮反应生成聚苯乙烯磺酰腙,这些腙在碱作用下分解生成烯烃或重氦化合物,同时伴有少量碳骨架重排。反应的实质是由醛或酮制备烯烃或重氦化合物。
Copoly(styrene-divinylbenzene)sulfonylhydrazine reacts with aldchydes and ketones to form the copoly(ST-DVB)sulfonylhydrazone derivatives (Ⅲ).When heated under alkaline conditions (sodium in ethylene glycol),Ⅲ elease the corresponding alkenes oraryldiazomethanes,sometimes produce the rearrangement of the carbon keleton.The recov-ered resin could be directly reused although its capacity was slightly decreased.
