Abstract α,α′-bis(substituted benzylidene)cycloalkanones were efficiently prepared from variously substituted aldehydes and cycloalkanones in water by using ash of pomegranate peels (APP) as a catalyst. The APP-catalyst was obtained from bio-waste by simple thermal treatment to dry peels of pomegranate fruit and formation of its active phase was confirmed by FT-IR, XRD, XRF, EDX, SEM, DSC-TGA and BET
摘要 以石榴皮(APP)的灰分为催化剂,由水中的各种取代的醛和环烷酮可高效制备α,α'-双(取代的亚苄基)环烷酮。通过简单的热处理将石榴果皮干燥即可从生物废料中获得APP催化剂,并通过FT-IR,XRD,XRF,EDX,SEM,DSC-TGA和BET技术证实了其活性相的形成。分析表明,本发明的催化剂具有促进所需产物合成的碱性位点。我们协议的主要吸引力是利用高度丰富的生物废物衍生催化剂,并在最短的反应时间内获得良好至优异的产率。通过在低温下将等摩尔量的芳族醛和1-四氢萘酮缩合,该绿色方案进一步扩展为结构上多样化的2-亚芳基-1-四氢萘酮。 图形摘要
