efficient method to prepare multi-dynamic acyl (aryl and heteroaryl) hydrazonesfrom acyl hydrazides has been achieved by using mild base K2CO3 and commercially available Co(OAc)2.4H2O salt as catalyst under mild reaction conditions with methanol as solvent. Additionally, the E/Z photoswitching behavior of some of the new acyl hydrazones has been witnessed by UV-vis spectroscopy.
以弱碱K 2 CO 3和市售Co(OAc) 2 .4H 2 O盐为催化剂,在温和条件下,实现了一种原子经济且高效的由酰肼制备多动力酰基(芳基和杂芳基)腙的方法。反应条件以甲醇为溶剂。此外,一些新型酰基腙的E/Z光开关行为已被紫外-可见光谱证实。
